BARCELONA (Reuters) - Diego Costa's return to Atletico Madrid has not been plain sailing, but it rarely is with the former Chelsea striker who has helped his Spanish club within reach of their third Europa League trophy.

Since rejoining his former side in September, and after sitting out three months because of Atletico Madrid's ban on registering players, Costa has only three league goals in 14 appearances.
