chelsea have drawn at anfield against liverpool. a shock defeat for arsenal means they have still stretched their lead at the top of the table. mps want to see lord coe again after he is accused of withholding information aboutjust how much he knew about russian doping. good evening, it's been a night of missed opportunities at the top of the premier league. it was 1—1 at anfield tonight as leaders chelsea were held by liverpool. despite missing what would have been a winning penalty and drawing for only the second time this season they have still stretched their lead

in the table to nine points, as arsenal and spurs both slipped up as well. we'll head live to anfield in just a moment but first here's nick parrott with the story of the match. jurgen klopp has been making heavy weather of things at liverpool of late. defeat to chelsea would be the fourth in a row at anfield making it that worst home on the 93 years, but the men in red made the better start dominating early possession and almost going ahead. the premier league leaders weathered the early storm when luis released a lightning storm. it appeared they didn't hear the referee's whistle, not that they could have done much to stop that free kick. liverpool weren't about to roll over. this should have got them back on level terms. if that made anyone think it wasn't going to be their night, they made the most ofafar be their night, they made the most of a far harder opportunity. back

from the africa cup of nations, mane was sent on to supply a winner, but first costa with a penalty. they almost made up for that in the final minute but liverpool held on to stop the rot although it still looks like no one will be able to stop chelsea's marched at the title. let's get more on the match now from our reporter ade adedoyin. ade, i'm guessing liverpool will be happier with that point? yes because against the run of three defeats at anfield and more importantly they delivered the kind of performance jurgen klopp importantly they delivered the kind of performancejurgen klopp had been asking for with more passion and intensity. when you consider the months liverpool have hard, losing to the likes of swansea and southampton, to get one point off a

chelsea side who have been in top form is a pretty decent result. let's hear from both form is a pretty decent result. let's hearfrom both managers now. we played good football, it was flue nt we played good football, it was fluent and aggressive, we were good organised, all of that stuff. you cannot create chance after chance against chelsea but you can keep them under pressure and that's what we did. i liked it a lot, i will performance, and i think the point is what we deserved at least. we have many opportunities to score the second goal. i'm pleased for the performance. it is not easy to play against liverpool and in this atmosphere i am very proud for my players, for the way they played with this atmosphere, it is not easy. 50 that result keeps them ten points behind chelsea, and they will

hope to build on this result when they travel to hull at the weekend. as for chelsea, a london derby against arsenal on saturday. thanks very much indeed. arsenal could have cut chelsea's lead but were stunned by watford at the emirates. they lost 2—1, their first league defeat at home since the opening weekend of the season. both watford's goals came inside the first 15 minutes from younes kaboul and troy deeney. alex iwobi poulled one back after an hour and the gunners also hit the bar but couldn't stop watford, celebrating theirfirst league win in eight an especially poignant victory with the funeral of their greatest manager, graham taylor taking place tomorrow. mentally m e nta lly we mentally we are ready for the challenges and maybe subconsciously 0k challenges and maybe subconsciously ok let's play our game, and it was not enough. on top of that, we were punished, we were unlucky on the first goal. it was deflected, then a soft free kick, but after that you

could see we responded, but it took usa could see we responded, but it took us a while to get into the game. the second half was all us and we were very unlucky not to come back or win the game. tottenham are up to second, above arsenal on goal difference, but they also dropped points. they had most of the possession and chances against sunderland but it was goalless at the stadium of light. the point lifts sunderland off the bottom of the table also on goal difference. four other results tonight, crystal palace have a first league win under sam allardyce beating bournemouth 2—0 but they remain in the relegation zone. sam vokes scored the winner for burnley against leicester. middlesbrough and west brom drew i—i. swansea have back to back wins for the first time this season. they beat southampton 2—1. gylfi sigurdson the matchwinner again. match of the day is on at 10.45

in england and northern ireland, 11.10 in wales, and 11.45 in scotland. we will see how hull get on against manchester united. a good win for palace but swansea's win at home to saints keeps them two points above the relegation zone. there were two matches in the scottish premiership tonight, hamilton and inverness had been level on points at the bottom. accies 3—0 win was their first in 12 in the league. motherwell are into the top half of the table after beating ross county 2—1. hull city's ryan mason says he's "lucky to be alive" after having

surgery on a fractured skull sustained in the premier league match at chelsea. mason was carried off the pitch after clashing heads with chelsea's gary cahill and underwent surgery that night. releasing a statement this evening he said "it has been an emotional roller—coaster and i feel lucky to be alive, but i'm happy to say i'm now at home resting and recovering. i would like to say a special thank you to all the medical staff at hull, as well as the medical team at chelsea and of course the fantastic treatment and support i have received from all of the staff during my stay at st, mary's hospital. i will now be taking each day as it comes and concentrating on my recovery." that's all the football for now, we'll have the transfer deadline day news at the end of the programme. there are calls for lord coe to meet with mp's again after new emails seem to confirm that he did know the details of doping allegations in athletics four months before they became public in a tv documentary. the president of world athletics had told a parliamentary select committee that he was unaware of the specifics of the russian doping scandal. there are questions the committee

would like to put to him, but it is clear he was far more aware of serious allegations around doping corruption in athletics than he let on when he came to the committee in december 2015, and it asks the question of whether he should have done more to inform himself more folly of those allegations and act upon them. just four days before the start of the six nations championship, jonny sexton has been ruled out of ireland's opener against scotland. the fly—half has failed to recover in time from a calf injury that he picked up earlier this month while playing for leinster. peter o'mahony also misses out on the murrayfield match with a hamstring problem. there's a double blow for wales in the pack lock luke charteris will miss the match against italy in rome on sunday. he has a fractured bone in his hand.
