Chelsea have informed Atletico Madrid that they will recall Alvaro Morata from his loan spell, unless they sign him permanently this summer, according to the UK Telegraph.
Morata joined Atletico in January, with his loan deal running until June 2020.
However, the Blues are now demanding that Atletico sign Morata for £50million during this transfer window.
If the La Liga side failed to buy Morata, Chelsea, who are unable to sign new players this summer due to a transfer ban, are likely to exercise their option to recall the 26-year-old.
Morata scored six goals in 17 appearances for Atletico last season.
