Atletico Madrid are growing increasingly concerned that Chelsea will not buy Joao Felix in the summer, according to reports.
Felix has struggled for consistency since joining the Blues on a half-season loan deal in January, scoring just twice in 15 games for the club.
He signed for Chelsea to help try and solve the Blues' goal scoring problem, but no solution has been found with the side failing to find the back of the net in five of their last six games.
There was no buy option included in the deal completed in January, but Atletico are keen to offload the forward to the London club.
