The Spaniard is currently with Manchester United, and performed admirably against Real Madrid this week, fuelling speculation he could replace Victor Valdes long term at the Camp Nou.

"De Gea is a great goalkeeper, but it's down to Zubi [Andoni Zubizarreta]," he said. "I personally really like him as a keeper.

"It was a great game, and the tie is very open. We now have to think about our own game. The match at Old Trafford should be a good one, too."
