Spanish giants Atletico Madrid are said to be increasingly concerned that Chelsea will not buy Joao Felix.
The Portuguese forward is on loan at the Stamford Bridge club since January.
While Felix has shown flashes of his talent, he has flattered to deceive in most games in the Premier League.
Per Cadena Ser, the La Liga outfit are now worried that Felix will be back with them at the start of next season.
He does not have a good relationship with Atletico coach Diego Simeone.
A summer transfer is the most likely outcome, but Felix's performances this season mean the bidding war that Atleti want is not likely to happen.
Chelsea may do a deal, but only for a much lower fee than has been mooted in the press.
