Xabi Alonso believes Real Madrid boss Jose Mourinho is 'made for' games like the clash with Manchester United but is expecting a tough test at the Bernabeu.
The two European heavyweights will collide on Wednesday night when the Primera Liga giants host United in the first leg of their last 16 UEFA Champions League tie.
Alonso feels manager Mourinho thrives on blockbuster encounters like this one but knows Sir Alex Ferguson will be just as up for the challenge.
He told The Times: "Mourinho is made for games like this one against United.
"The way he prepares the game, the way he analyses the opponents, the way he approaches us in terms of giving us a psychological edge and extra motivation, he loves these occasions."
Ex-Liverpool man Alonso added: "They have that United thing: it is hard to put into words, but it means that they are always competitive against anyone.
"It is probably a Ferguson thing, because he is them and they are him, the team has taken on his psychology.
"He is that edge and that transmits from him to his players, something that I saw at first hand during my Liverpool years.
"So we are expecting a very intense, difficult tie."
