Barcelona coach Pep Guardiola has played down claims by Real Madrid counterpart Jose Mourinho that the Catalan club were "super-favourites" to beat Chelsea in the UEFA Champions League semi-finals. Mourinho guided his team into the last four with an aggregate success over APOEL Nicosia on Wednesday night and then virtually wrote off the chances of meeting his former club in next month's final in Munich. However, Guardiola will not be taking Roberto di Matteo's rejuvenated Blues lightly in the two-legged tie later this month.Speaking at his press conference ahead of tomorrow night's La Liga game at Real Zaragoza, the 41-year-old said: "I'm thankful for the confidence he has in us, but all four teams in the semi-final have a chance. "It is a team of great experience, that has fantastic players all over the pitch. It is one of the great teams in Europe. It is a team with history in recent years in English football. "Competing in the Champions League, they have always been there and have shown themselves capable. We will have to produce good performances to reach the final. It is clear that in the semi-finals of the Champions League there is no rival that you can think will be easy."
