Butragueño: "Favourites is a dangerous word"
"They are a German side and they will be extremely motivated. We have to play very well. We know how costly it can be to make a mistake in Europe."
Nyon
Relief after the draw? "In the quarterfinals the opponent is always strong. They are a German team and they will be extremely motivated. We have to play very well. We know how costly it can be to make a mistake in Europe. We have to get a good result in Germany. It is an advantage to play the second leg at home but we also have to do a good job in Germany."
Wolfsburg: "They finished above PSV and Manchester United in the group stage, they knocked out Gent... they are a dangerous team."
Favourites: "That is a very dangerous word. The tie is after the international break. We'll have to see how the players are when they come back."
Barcelona-Atlético: "If we had been drawn against them we would have approached the tie in the same way."
