Atletico Madrid left-back Filipe Luis has admitted that it will be "tough" for his side to win the Champions League final this weekend.
Diego Simeone's side face Real Madrid in the conclusion of the tournament in Lisbon, fresh from their La Liga title triumph on Saturday.
"They have a very large team and can change the system in each game. Their players can play in several positions, so it's going to be tough," he told reporters at a press conference.
Atletico are expected to be without leading scorer Diego Costa for the final of the European Cup, but Arda Turan should return.
