It has emerged that the Belgian international is being seriously considered as a target by Graham Potter’s side, despite only making the £33m switch to Everton in the summer.
Financial Fair Play concerns mean Onana could be sold, although Chelsea may also have to fend off interest from Arsenal and Newcastle. At 21 years of age, the midfielder does fit the profile, but there are question marks about his technical ability and whether he suits Potter’s style of play.
