MANCHESTER (REUTERS) - Pep Guardiola said there was no other reason why he has stayed on as Manchester City manager for so long other than the fact his team keep winning but he is no rush to sign a new contract.

The Spaniard's contract runs out at the end of next season and should he see that deal through, Guardiola will have been in charge of City for seven seasons, three campaigns more than he oversaw at his native Barcelona.

City are top of the English Premier League standings, nine points clear of second-place Liverpool going into their clash with Brentford on Wednesday (Feb 9), and are on course for their fourth Premier League title under Guardiola.

"I am here so long because we won a lot and we're winning a lot," the Catalan told a news conference on Tuesday.

"Otherwise, I will not be here in front of you after six seasons. We are comfortable - both the club and myself. And that's why we continue, it is no more than that.

"We still have a 1½ contract, which is a lot of time considering how world football is. We see how many managers were sacked, not just here in England, but everywhere.

"So that's why I'm just thinking about the next game as 1½ (years) is a lot of time in football."

Guardiola also made light of videos circulating on social media showing several City players outside a bar in Manchester on Sunday night.

"I'm so upset because they didn't invite me," he said.

"The video didn't show what did or didn't happen. All of them were perfect, but they will be fined because they didn't invite me."

Brazilian forward Gabriel Jesus is the only player doubtful for the Brentford game due to injury.
