Patrick Vieira denies Manchester City's squad is overloaded.

Vieira, who won three league titles with Arsenal and four with Inter Milan, insists current Premier League champions Chelsea are proof that an extensive team is needed to secure silverware.

"When you look at the Chelsea bench they also have a good team on the sidelines," Vieira told the Manchester Evening News.

"But if you want to go from the start to the end you need everyone, and for everyone to be fully committed.

"Anything can happen in the first few months. Eleven players will start the first few games, but there are so many games to play, in so many competitions."
