Manchester City full-back Pablo Zabaleta feels his team have been rattled by speculation since confirmation Pep Guardiola would take over as manager next season.

The Bayern Munich coach's three-year deal with the Premier League giants was confirmed in early February and potential arrivals and departures have been talked about since.

Zabaleta, whose team sit fourth in the table ahead of the derby at the Etihad Stadium on Sunday, said it had impacted City.

"We know it is not easy for everyone," the Argentinian said.

"There is a lot of speculation about new players coming in and players going out. What we have got to do is focus more."

Manuel Pellegrini's men are 15 points behind league leaders Leicester City, who have played two games more.
