Arsenal midfielder Alex Oxlade-Chamberlain is on the brink of joining Premier League champions Chelsea.
Oxlade-Chamberlain, 24, will be out of contract next summer and has refused to sign a new deal at Emirates Stadium.
The England international has started every game for the Gunners so far this season, including Sunday’s 4-0 defeat at Liverpool, when he was substituted.
Chelsea have declined to comment but it is understood they have agreed a transfer fee with their London rivals.
Liverpool have also shown an interest, but the former Southampton player is set to move to Stamford Bridge.
Oxlade-Chamberlain would be Chelsea’s fifth major signing of the summer following the arrivals of striker Alvaro Morata, goalkeeper Willy Caballero, defender Antonio Rudiger and midfielder Tiemoue Bakayoko.
Chelsea manager Antonio Conte had made it clear he wanted to add further to his squad before the transfer window closes on Thursday.
Oxlade-Chamberlain, who has made 198 appearances for Arsenal since joining them from Southampton in August 2011, would be the first arrival since the Italian said he wanted to sign four more players.
The Blues have allowed a host of players – including defenders John Terry, Nathan Ake and Kurt Zouma, and midfielder Nemanja Matic – to leave this summer, while last season’s top scorer Diego Costa has been told he can leave.
They have won two of their opening three Premier League matches.
Arsenal, meanwhile, have lost their past two games, including Sunday’s defeat at Anfield.
Like Oxlade-Chamberlain, forward Alexis Sanchez and midfielder Mesut Ozil are also out of contract next summer.
