Saul Niguez is expecting Diego Costa to make a huge impact at Atletico Madrid.

Atletico lodged a €50m offer to Chelsea this week for the AWOL striker, with the view to signing him in January.

Atleti ace Saul declared: “In the locker room, we do not talk much, but we know what he is capable of.

“He knows this place, he does not need to adapt, he knows the teammates, the requirements of the club.

“If he comes, he will bring an enormous impact to us.”
