Striker Diego Costa has completed his move back to Atletico Madrid from Premier League champions Chelsea.
The two clubs agreed terms last week and the 28-year-old Spain international passed his medical on Monday.
However, he will not be able to play for the La Liga side until 1 January, when the club's transfer window ban comes to an end.
Costa left Atletico for Chelsea in 2014 and scored 59 goals in 120 games appearances for the Blues.
