Graphic: Final four in the Champions League

Barca coach Luis Enrique insists his side's clash at home to Bayern Munich is about far more than Pep Guardiola's return to the Nou Camp.

Guardiola, now the Bayern chief, is preparing to go head-to-head with the club with which he is synonymous for the first time tomorrow night.

He won 14 titles - including two Champions Leagues, during four golden years in charge - having also enjoyed a glittering playing career.

Before that, Real Madrid manager Carlo Ancelotti is back in Turin tonight at the club he was in charge of from 1999 to 2001, bidding to become the first boss to retain the Champions League.

They face a Juventus side who claimed their fourth successive Serie A title at the weekend and are eyeing their first Champions League final in 12 years.

Ancelotti said: "I believe that the semi-finals will be close. It has been a few years since they reached this stage of the competition, but they go into the game full of confidence.

"They are a very strong side, with a lot of experience and high-quality players. Winning here is not so easy.

"The important thing is to try and play and well as possible showing all of our quality. We are having a good spell.

"The team is confident and all of the players are doing well. They are going to try and do everything as well as possible."

Guardiola is hoping to get one over on Barca, now managed by his former team-mate Enrique, standing in the way of a Champions League final.

But Enrique said: "We aren't going into this as a game against Pep. He is the No 1 for what he has achieved and he's a friend.

"This is such an important game for all Barca fans that it should be more important than any specific people.

"It's nice for the players to meet Guardiola again, but they know that this game is more important than just that.

"Guardiola knows most of our players but I don't think that will be decisive. There are many other factors."
