The visitors leveled eight minutes later through Fernandinho only for Raheem Sterling's own-goal to leave it trailing once again.

That goal came just eight minutes later as Nolito fired home from close range after Sergio Aguero's effort had been blocked.
"It was difficult for us," Guardiola told BT Sport.
"I'm happy with the reaction from the players, it's not easy to score three goals a
