premier league game. and back to where it all began. roger federer delights his home crowd on his return to the swiss indoors in basle. hello and welcome to the programme. more on monday's surprise result from the english premier league to come. but first, a landmark study in the uk suggests ex—professional footballers are three and half times more likely to die from dementia. research over nearly two years by a specialist brain injury group at scotland's glasgow university said there was also a rise in the risk of alzheimer's, motor neurone disease, and parkinson's. the study began after claims the former england forward jeff astle, died due to repeated head trauma. the bbc‘s health editor, hugh pym, has more. heading has always been part of football, but is it good for players‘ health? a new study has found football professionals born before the mid—‘70s were more likely to die

with dementia than the general population, though it doesn't try to say exactly why. how many times have you seen two players go up to compete for the ball and have managed to collide heads, get a head injury? so, that's the kind of risk that is there. so, what we're saying is, let's just take that one changeable thing we can do, which is just cut down the risk of head injury, cut down the risk of head impacts and that may make a big difference long term. commetator: astle nodding it on... jeff astle developed dementia and died in 2002 at the age of 59. a coroner ruled that heading had contributed to the cause of death. his wife and daughter have since campaigned for more research and are frustrated it's taken so long. that coroner's ruling was a landmark ruling and in any other industry, it would have had earthquake—like repercussions for that particular industry. but not football. today at wembley, i asked the english football association's medical chief why the research hadn't been launched sooner. it's difficult for me to speak

about what's happened historically. i've been working at the fa for three years now and in that time, i've experienced nothing but enthusiasm from people around me to take this on and to get this research done. the football association says this is an issue for the global game to address and more research is needed. but fans and players would expect the authorities here to be seen to be taking a lead. the fa, which funded the new research, highlights its finding that former professionals were less likely than others to die with lung cancer and heart disease, but the association now says children should limit heading practice and there's a sense in some quarters that the report must serve as a wake—up call for football. hugh pym, bbc news. arsenal missed the chance to move third, in the english premier league on monday evening. they were beaten 1—0 at sheffield united. lys mousset, making his first league start for the home side. got the goal, after half

an hour, to move them into the top half of the table. arsenal enjoyed the majority of the possession but couldn't make it count, their boss unai emery admitted his opponents defended well. the second half i think the fans more deep and be controlled better the match because on the pitch, there was less space and... we capped three or four chances to score and to roll the match and more. but they are a very strong defensive team. we deserve to win a tight game. we created some good chances and new... we knew that the amount of quality they have on show. it was good to get our noses in front and to hang

onto something and we did. but i think we got the balance right tonight and we had to put in a big performance and guinea pig results and we certainly have done that. virgil van dijk is one of seven liverpool players named on the 30—man shortlist for the 2019 ballon d'or. the dutchman is one of the favourites to win the award. after liverpool won the champions league, he was named the uefa player of the year in august. last year luka modric ended a seven—year spell of dominance by cristiano ronaldo and lionel messi. both of those two, rather predictably, are on the shortlist once again. roma have apologised to sampdoria midfielder ronaldo vieira after he was racially abused by fans on sunday. there were audible monkey chants from the visiting supporters, and roma have since issued a statement in apology.

hello there. pressure will be building in for tuesday morning. so it looks like many places will start dry. you can see this area of high pressure pushing in from the south west keeping this weather front at bay mainly affecting the far north of the country to start the day. we will have lost that weather front across the south—east, so drier there too. so it becomes quite a chilly start to tuesday with some mist and fog around when skies clear. those temperatures really drop. don't be surprised if you see scenes like this across central and southern parts of england and wales to greet us this morning. now, that mist and fog could only go on for a few hours but it should tend to lift and break and we should see a good deal of dry weather with some sunshine across england and wales and a vast improvement across the south—east. more cloud further north certainly for scotland and northern ireland. most of the rain to the far north with many places staying dry. temperatures of 12—15 degrees in the south which will actually feel quite pleasant.

and as for tuesday night, it stays dry with variable cloud across england and wales. stays breezy for scotland and northern ireland with rain tending to flirt with the north—west corner. temperature—wise, chilly in one or two spots particularly where skies clear. so, on into wednesday we hold onto the fine weather i think across much of the south—east. we have this weather front still bringing wet and windy weather to the far north—west and that low—pressure system across spain and france bringing a lot of rainfall, mayjust influence the weather across the south—east. a weather front here sending more cloud, perhaps one or two showers. for the north and the west, it stays windy. outbreaks of rain which will become more persistent in parts of northern ireland, western scotland but in between again a slice of dry weather. those temperatures 12—15 degrees. as we head on into thursday, it looks like that weather front in the south—east may bring a little bit of rain but we have got low pressure to the north—west which will push in to bring a spell of windy weather here. now we could see gales or even severe gales for a time across western scotland.

showers and even longer spells of rain here. one or two showers further south, particularly in the south—east where we will have that weak weather front. in between, some good spells of sunshine and again those temperatures are on the low to mid—teens celsius. low pressure then clears off to the north to end the week. we will see something a little bit drier once again but then we look to the south west, this new area of low pressure will slide in to bring increasing cloud and rain throughout the day. but we start friday off on a dry note for many with some sunshine, a few showers in the north which will be wintry on the hills. there will be some cold air across northern areas though as this winter and windy weather pushes northwards. we could see some snowfall on the high ground of scotland but it will be milder in the south.
