Chelsea have been offered the chance to sign West Ham forward Mohammed Kudus.
The Blues have not said no at this stage and are considering whether to add the 24-year-old to their list of attacking targets.
During discussions, Chelsea were asked about the potential availability of their goalkeeper Robert Sanchez.
Kudus open to leaving after rejecting Saudi move
Kudus turned down the chance of more than tripling his salary by moving to Saudi Arabia.
A Saudi Pro League club were willing to pay close to West Ham's £70m valuation to sign the player, but he does not want to move to Saudi Arabia at this stage of his career.
However, he is set to leave West Ham this summer as Graham Potter reshapes and refreshes his squad.
The player is aware of the situation and is open to leaving.
West Ham would expect to almost double the £38m they paid Ajax for him two years ago.
The Hammers have been offered players in part exchange, but that could increase their wage bill - if, for instance, they were to take three players as part of a deal from another club.
The Ghana international is ambitious, and clubs in the Champions League are likely to be options.
