Stoke City will demand Victor Moses as part of any Chelsea offer for goalkeeper Asmir Begovic.
The Telegraph says the Potters are expecting a formal bid from Chelsea for Begovic and will ask to have Moses included in any deal.
Begovic will cost around £8 million as he has only one year left on his contract, though Chelsea must convince the Bosnian that he will play enough games as understudy to Thibaut Courtois.
Stoke have identified Moses as a priority signing this summer and hope to agree a deal that will guarantee them cash plus the Chelsea winger in return for Begovic.
