Man City keeper Joe Hart dropped by Pep Guardiola, Kolarov at CB

Pep Guardiola dropped Joe Hart for his first match as Manchester City manager, raising further doubts over the England international's future.

Willy Cabellero got the nod in place of Hart for the visit of David Moyes' Sunderland on Saturday evening.

John Stones makes his debut in the centre of defence, but lines up alongside left-back Aleksandar Kolarov in a central position. Yaya Toure was also not included in the City squad, despite being fit.

Asked about how important Hart was to his plans in the lead up to the game, Guardiola told a news conference on Friday: "It is not really the time to talk about that the markets

"Joe is a player I'm so happy about his qualities, about his behaviour and what he means to this club. After we are going to decide inside the doors. Now, he is a player of us."

Guardiola has signed eight players so far but Hart could be part of an exodus of players in the final weeks of the transfer window. And the Catalan says City could remain active in the market.

"Aug. 31 is the last day [of the transfer window]," he said. "We are going to see at that time which players will stay, which players are going to be loaned, which are going to be sold and which players are coming.

"We are going to see, these three weeks, how is the game, how is the team, how is the smell. With Txiki [Begiristain], with the chairman, we are going to talk about that. We are going to decide."

Elsewhere, Jermain Defoe was passed fit for Sunderland while Moyes selected on-loan Manchester United forward Adnan Januzaj on the bench.
