Manchester City boss Manuel Pellegrini criticised his team's defending after they laboured to victory over Viktoria Plzen in the Champions League.

City were twice pegged back by the Czech minnows at the Etihad Stadium before late goals from Alvaro Negredo and Edin Dzeko secured a 4-2 win in the Group D encounter.

Sergio Aguero, from a penalty, and Samir Nasri had both put City ahead but Plzen responded each time through Tomas Horava and Stanislav Tecl.

Goals have not been a problem for City - with 22 now scored in the last four home games - but questions continue to recur about the defence, particularly in the continued absence of captain Vincent Kompany.

Pellegrini said: "We can attack and we can score four goals, but without giving (away) as many chances as we did today in defending.

"One of the most important things to be an attacking team is to know how to defend well. Today we did very, very bad.

"I am talking about the whole team. I think the whole team must know how to defend.
