In the last half an hour, they have reached an agreement. £40 million. Alex 0xlade chamberlain needs to undergo a medical and agree personal terms but the proposition is a six Year Contract.

They will not wa nt to other player as well. They will not want to see Alexis Sanchez go. He could join Manchester City . Alexis sanchezis could join Manchester City . Alexis sanchez is entering the final year of his contract. We know that Manchester City want. We know that he would like to leave arsenal. But are resisting that as strongly as they can. Manchester city had a £50 million bid rejected yesterday. Arsenal will only countenance a huge offer, much higher than £50 million, and with a player, preferably to them, raheem sterling, coming in the opposite direction. Man city dont wa nt opposite direction. Man city dont want any players to leave but arsenal will let deal happen if i replacement comes. They have signed a left back this year and let one go.

We have yet to see in a peer for everton. Everton have an asking price of around £50 million for ross barkley, even though you may has one year remaining on his contract. Chelsea have bid in the region of £25 million. Quite like danny drinkwater, they have to meet someone drinkwater, they have to meet someone in the middle. And everton, if they do not get the feeling they want, will hold ross barkley to the final year of his contract. It is a big 24 hours for you and i was here that the bbc sport centre.

I think the schedule is a long season, no doubt about it. There are ways that we plan events, and we have talked about maybe one event having a combined final to have more teams playing but no extension to the season.

But she was suspended, she fulfilled as then her sentence and came back. Is she a good role model for the sport . Maria is wellknown in the sport. She has lots of fans and and plays great tennis.

Now, a pitchside saliva test for concussion could be possible in the next five years if a new study into the issue is successful. Throughout this season, players in rugby unions english premiership and championship will provide samples which will be analysed by a team from the university of birmingham. Theyre looking for biomarkers, tell tale signs within cells which are released when the body suffers trauma. 0ur reporter patrick geareys been to see how it works. Welcome to the twickenham treatment room. It has seen more than its fair share of concussions over the years. This season, for the first big double header fixture here, players will have their saliva taken if they suffered a head injury. It is part ofa suffered a head injury. It is part of a big study into concussion. Here to tell us about it is a professor from the university of birmingham leading the study. What will happen ifa leading the study. What will happen if a player comes in with a head injury . The player will be removed for assessment, as they are now. They have ten minutes for that particular assessment. As part of that process for this season, during any premiership, championship match, they will also be doing an additional test. It is very straightforward. They will actually just be asked to collect about two millilitres of saliva into a special pot, which is actually a sophisticated piece of equipment. That bottle is collected and analysed in labs at the university of birmingham. With that data, the endgame is to have a hand held device that would tell us instantly whether a player has been concussed . Absolutely. The ultimate goal is to have a portable pitch side device because it is all very well and good having a biomarker if you want to test that can give you a diagnosis of concussion but still requires a lab to analyse it for a couple of hours, but ultimately, what we want is to have a portable, pitch side test that can be used by the doctors ina test that can be used by the doctors in a professional game potentially pavement, if this works as well as we hoped. Potentially, this is a prototype of a device that we hope is going to be able to diagnose concussions. So the player would be providing, if you want, a drop of saliva. Then the strip is inserted into a reader and the reader within a couple of minutes should be able to give you the diagnosis of concussion. Confirming a concussion has called, removing the player permanently, or disproving the concussion, so the player can return to the game. Fascinating. This trial will take place in all premiership and championship games this season. The results could begin changing. Indeed. Britain has won their first world judo championship medal for seven years as nekoda davis took bronze in the 57 kilogram category in budapest this afternoon. Davis was leading the reperchage final against panamas miriam roper but the win was secured when her opponent fell awkwardly and damaged her knee. Euan burton won britains last world medal in tokyo in 2010. I think it will sink and later on when i have the medal round my neck. But, yes, incredible feeling and one of my dreams come true. U nfortu nately, of my dreams come true. Unfortunately, the circumstances with how the contest ended were not the best. Does that take anything away from the medal . Not at all. I was two scores are away from the medal . Not at all. I was two scores are up away from the medal . Not at all. I was two scores are up and i feel
