Two of La Liga's most in-form sides take to Ipurua on Saturday, although Eibar have lost all their previous meetings with Atletico Madrid in the top flight.
Eibar boss Jose Luis Mendilibar on facing Atleti: “It's difficult to play them. For them, to play well means not putting together 40 passes in a row but rather to compete.
“They know how to wait for the right moments, they don't get nervous and they always play the same football, even if they're still at 0-0 towards the end of a game.
“It's the best time to play against Atletico. I hope we can compete, go toe-to-toe with them and see if we can win.
“We're not going to change the way we play against them.”
Atleti boss Diego Simeone on their transfer ban and being drawn Sevilla in the Copa del Rey: “The most difficult thing was not being able to sign players, getting the first-teamers to grow and improve and the youngsters to get on the train of opportunity.
“That was very tough. Now I can manage important players in the best way, and we can keep going like we have been.
“Seviilla? They're a big side and a cup team, with very good players and a change of Coach not long ago.
“[Montella] has a very good track record for the work he did at Roma, Fiorentina and Milan, beyond his recent sacking. Surely for the club and fans, these will be very important games.”
