Chelsea lost Diego Costa's goals in the summer, but they seem to have found a more than adequate replacement in Alvaro Morata.
Costa re-joined Atletico Madrid, the Blues' Champions League opponents on Wednesday night, initally on loan until the end of season ahead of a permanent £58m transfer. However, he won't be able to play until January due to Atletico's transfer embargo.
In his first season at Stamford Bridge, he scored eight goals in his first six Premier League games and ended the 2014/15 campaign with 20 overall. Morata, meanwhile, has scored six in his first six games since his £65m summer move from Real Madrid.
