Pep Guardiola has revealed that he is unsure if he will continue as coach of Barcelona beyond this season.

The Spaniard's deal is due to expire in the summer and as yet no agreement has been reached over an extension.

Despite winning 13 trophies since taking over the club in 2008, Guardiola has admitted that a lack of motivation could see him move on to find a new challenge.

"I would have liked to have made my decision earlier but it still isn't clear to me. It's a personal question. I need to find the motivation to continue and it still isn't clear," said Guardiola.

"Right now I prefer to take a little more time. I don't want to say yet, I need to feel certain.

"If people respect that, great, if not, too bad. This is the situation there is, I've already answered many questions about it and I have nothing else to say."

Barca's vice-president Josep Maria Bartomeu said earlier today that he expects Guardiola to stay put.
