Chelsea will step up their efforts to sign Alex Oxlade-Chamberlain next week after securing a deal for Alvaro Morata.
The Premier League champions paid a club-record fee to bring in Morata from Real Madrid on Friday and Arsenal midfielder Chamberlain is now in their sights, according to Sky sources.
Arsene Wenger has said he "100 per cent" expects Oxlade-Chamberlain to stay at the Emirates, but the player is inside the final year of his contract.
And Sky Sports News understands the 23-year-old - also wanted by Liverpool and Manchester City - told Wenger this week that he has no intention of signing the extension currently on offer.
Arsenal play Chelsea in a Beijing friendly on Saturday before flying back to England, and the Blues plan to open talks about a transfer within 48 hours of the Gunners' Sunday return.
