at the australian open where we have an unusual reason for a stop in play today. manchester united lose at home to burnley, hurting their chances of a top four finish. and injust under two hours, zion williamson is set to make his nba debut for the new orleans pelicans. hello and welcome to the programme where we start with tennis at the year's first grand slam in melbourne. the australian open has moved into day four and there for us as always isjohn watson. there's been a bit of an issue with the outside courts in the morning, john, what's the situation? what has happened? organisers and many people are saying this could be the first time this has happened in grand slam history. essentially, play on the outside courts has been delayed here for three hours because of dust and mud and a lot of dirty

sediment which has built up on the outside courts. the reason being, there were rain showers last night that got mixed with dust storms brought across melbourne park by the strong wind. that has left a dirty sediment all over the outside courts and the organisers are having to clea n and the organisers are having to clean that up now because the courts are not fit for play and they are not fit to allow spectators on at the moment, causing a three—hour delay. possibly this is the first time we think this is happened in grand slam history. of course we have seen play on the main show courts and as far as the rob lever arena is concerned, ga been muguruza againstan arena is concerned, ga been muguruza against an australian hopeful. —— garbine muguruza, a former world number one on rod laver arena first up against home favourite ajla tomljanovic, followed by second seed karolina pliskova. while in the night session

rafael nadal continues his bid for a second title here but a 20th grand slam title overall, something he says he's not concerned about, though. this variant of will also be playing. on margaret court arena — sixth seed belinda bencic is playing former french open champion jelena ostapenko. men's fourth seed daniil medvedev follows on from that one while 2014 champion stan wawrinka features in the night session, as does fifth seeded ukranian elina svitolna in the women's draw. should we expect any shocks in the evening session later? possibly. we are looking out for them. we will see simona halibut in action later on. she faces harriet died, the first match in the evening session on the rob lever arena full what a moment for the young british player against the wimbledon champion and numberfour seed. against the wimbledon champion and number four seed. rafael nadal is last up on rod labour. we know a lot about him, don't we? made it through the final here last year and lost to

know that djokovic. you wonder, if we are going to see an upset it could come in the next round because he is potentially in line to meet net kyrgios if they get there. i don't think we will see an upset with simona halibut against harriet dart but let's hear from simona. being a top layer is an advantage and not so much an advantage and not so much an advantage because everybody wants to get you. but if you think about that you don't have time to think about yourself. so i try to focus on my game, to play what i want against herand then we game, to play what i want against her and then we will see. she comes into this after a good year last year and will certainly fancy her chances again —— of going deep in the tournament. talking about upsets and support for ayla tomljanovic. support also for nick kyrgios. interesting to say that he wanted to play on the melbourne park court which is where you get a lot of the

spectators with ground passes going in and it has a great atmosphere. he is in action there later on so he is thriving in playing in that special atmosphere out on court and he said himself that he feels he is playing for so much more this year than just himself, in light we have seen in recent weeks with the terrible bushfires in the devastation caused in australia. that is a big match to look out for later. manchester united have dropped ground in their race for a champions league spot after losing 2—0 at home to burnley. goals from chris wood just before half time and a wonder strike from jay rodriguez after the interval handed them the win — and watching at old trafford was ian dennis. a famous win for burnley, their first at old trafford since 1962, to inflict a damaging defeat on manchester united. a painful night. predictable as they toiled in the second half lacking creativity

against a well—organised only. united created opportunities that fell behind with woods taken goal after 39 minutes. rodriguez made two, 11 minutes into the second half. manchester united were desperate and they lacked ideas. on a night when the pressure increased both on and off pitch. at one point early on it felt like we we re at one point early on it felt like we were creating openings and chances we did not take them. so now it is one of... well, disappointment. hold our hands up, it was not good enough. the club is working behind the scenes to do deals and if they are right, it is a difficult time as well to do things injanuary difficult time as well to do things in january but for us, difficult time as well to do things injanuary but for us, i know difficult time as well to do things in january but for us, i know the clu b in january but for us, i know the club is working hard to get players in because we have been stretched, these players have been stretched and hopefully the injured players, when they return they can give us

something but there may be something, i can't tell you know. elsewhere, ayoze perez scored twice as third—placed leicester city beat west ham 4—1. jamie vardy limped off with a leg injury in the first—half — but it's not thought to be serious. and south korean striker son heung—min scored tottenham's winner in a 2—1victory over norwich — who remain six points adrift at the foot of the table. spurs are up to sixth. 13—time winners juventus are through to the coppa italia semi—finals after a 3—1win over roma. cristiano ronaldo opened the scoring for the home side in turin as he made it 13 goals in his last 10 games. rodrigo bentancur and leonardo bonucci added further goals before the half time interval and despite an own goal from juve keeper gianluigi buffon after the break his team made it through to a semi—final against either milan or torino. in spain, barcelona are through to the last 16 of the copa del rey — but only after surviving a scare against third tier side ibiza. antoine griezmann scored both goals for barca — including their stoppage—time winner — as they came from behind to win 2-1.

god. just blast his way across the court. workouts and strenuous. there were many times when i just wanted to punch a wall or kick a chair because it is frustrating. do not be able to move your body the way you want to, i've been making athletic movements, and it is tough, especially because i'm19 and it is tough, especially because i'm 19 and have yet to play my first game. it was tough. it was difficult. if you saw me meditating on the sidelines stop it has been very difficult. but it is finally here and i can finally go back out there. hopefully i can go out there and contribute. this is basketball. this is what i do and i have known since i was four. go out there, have fun and be with my teammates.

piece. these swiss sixth seed has beaten ostapenko. hello there. wednesday was a rather grey and gloomy day for most of us — misty and murky with some spots of drizzle. there were a few brighter spells, particularly eastern scotland and north—east england, and i think today's looking pretty similar — most places cloudy with limited spells of brightness. we've still got our area of high pressure, it's getting squeezed out as lower pressure's pushing in from the north and from the south. this weather front will be pushing to the north—west of scotland to bring outbreaks of rain. but it's going to be another very grey day. there could be some dense fog patches in places, particularly england and wales, and some of the cloud might be thick enough for the odd spot of light rain or drizzle. much like wednesday, it's probably eastern scotland and north—east england where we'll see the best of any brightness.

we could see a little bit as well across the south—west of england. for most of us, the winds will be winds but stronger in north—west scotland as that weather front moves in. there will be a stronger easterly blowing through the english channel. those temperatures, hovering around eight or nine for most, could see 10 or 11 in the brighter spots of north—east scotland. this weather front pushes further south with rain heavy on it as it continues to go south, but it tends to weaken and elsewhere a rather cloudy night with spots of drizzle and a bit of mist and murk and again a largely frost—free one because of the cloud cover. a few sheltered spots in north—east england and north—east scotland could turn chilly. friday will be similar sort of day. with our low of high pressure with us, it's going to be a rather grey and gloomy one with those temperatures around eight or nine degrees. that is how we are looking on friday but out of friday and into the weekend, we start to see some changes. low pressure starts to push into the north—west of the country. for england and wales, you'll still notice not many isobars around so another day of light winds here and quite a bit of cloud. further north—west, for scotland and northern ireland, it will be a breezier day and we'll start to that weather front pushing into the north—west of scotland. could be as well because of

the breeze mixing up the air, we could see some brightness for scotland and northern ireland but a rather cloudy day for most. those temperatures, 7—10. as you move through saturday night into sunday, that weather front begins to push eastwards, slowly sliding across the country and you'll notice more isobars on the chart for sunday. so it's going to be a breezeier day, or windier day, for us all, particularly in the north—west. this weather front moving eastwards will bring outbreaks of patchy rain, the odd heavier burst on it as it moves across england and wales. brighter skies in scotland and northern ireland but here there will have blustery showers and they will be wintry and quite cool over high ground, nine or 11 in the south—east. then as we head into following week could be unsettled. we could see a deep low bringing gales and a spell of wet weather earlier in the week.
