Atletico Madrid midfielder Saul Niguez says they can't be obsessing about Diego Costa.

Atletico failed to score in their 0-0 draw with Leganes.

Costa's January arrival is unquestionably a move to try and rectify such issues and Saul though maintains that improvements have to start before the Spanish forward arrives.

"Until January, he [Costa] will not be able to play, so we have to think about what we are doing, we have to trust the players who can contribute right now," he concluded.
