The Atleti 'keeper is happy to contest the trophy at either the Santiago Bernabeu or Vicente Calderon
Atleti last won the trophy back in 1996 and the Belgium international, who is on-loan from Chelsea, insists he does not mind where the final will be played, with a date or stadium yet to be decided.
"The Calderon is fine for the final because it will be half and half for the fans, whilst if we play at the Bernabeu it will also be fine because 40,000 fans will make it feel like we are playing at home," the 20-year-old told Onda Cero.
The youngster also tried to pick the positives out of his side's elimination from the Europa League, after losing to Rubin Kazan in the round of 16.
"We wanted to go far, but we do not have a large squad. Maybe we can pick up more points after the elimination, because we do not have to travel as much now and we have more time to rest.
"As a player, you want to win everything. The Europa League had given us a lot of joy. But it costs a lot to play a game every two or three days."
Los Rojiblancos currently sit second in La Liga with a two-point advantage over second-placed Madrid.
