Joe Hart insists Manchester City are focused on their title challenge despite the news that Pep Guardiola is set to join the club in the summer.
The England goalkeeper was at his formidable best as City beat Sunderland 1-0 at the Stadium of Light on Tuesday night to remain three points behind leaders Leicester City.
And Hart said he and his teammates are determined to win the Premier League before current boss Manuel Pellegrini leaves the club at the end of the season.
He told the club's website: "We're here to win titles, Manuel is here to win titles and that's what we're to try to do. We back him all the way and we love him as our manager.
"We appreciate we have a job to do this season, next season is next season."
It was a hard-fought victory for City, who survived a late onslaught from the Black Cats after Sergio Aguero had fired them into a 16th minute lead.
Hart made a number of fine stops with a first half reaction save to deny Jermaine Defoe in the first half the pick of them.
Hart added: "I thought Sunderland were fantastic tonight. If they carry on like that they'll have no problems at all.
"Yes, there were a couple of good saves but some fantastic defending at the end there -- their new lad [Whabi Khazri] whipped in some really dangerous balls and the boys put their bodies on the line for each other and for the manager.
"We're one and we stick together -- we keep fighting."
City face leaders Leicester City on Saturday and a victory would see them move to the top of the table.
Hart said: "Leicester have been absolutely amazing but it's all about doing what we do. Leicester's going to be a fantastic game and one that we're all looking forward to."
