Pep Guardiola has refused to be drawn on rumours he could end his long association with Barcelona after their UEFA Champions League final against Manchester United.
The Spanish coach spent almost his entire playing career at Barca and was in the side that won the European Cup for the first time in 1992, at Wembley.
Speculation has surfaced the 40-year-old could depart Camp Nou in the summer, but Guardiola declined to discuss his long-term future ahead of Saturday's Wembley showdown with United.
Guardiola said: "Leaving? We'll leave that for another day."
"Today is not the day to talk about that."
Barca have been installed as firm favourites against the side they beat comfortably in the final in Rome two years ago.
But Guardiola claimed the Catalans would lose if they merely repeated that performance this weekend.
"If we play as we did in Rome, this time we won't win," he said.
"We played worse in Rome than we wanted to. We need to play much better than in 2009 and this is the thing I've told my players over the past couple of days."
Guardiola revealed he had already decided upon his starting XI tomorrow, confirming both captain Carles Puyol and fellow defender Eric Abidal were fit if selected.
"There are obviously factors, variables," he added. "Ferguson said there were four or five different teams he could play.
"That shows how much talent is in that team.
"Strong points, they've got a lot of them. Weak points, they've got a lot of them too."
He added: "I'm worried about everything. Manchester United worries me.
"They have fantastic players, they're powerful, one of the most complete teams I've seen in all senses."
