Manchester City playmaker David Silva will be out of action for a month.

The Spaniard picked up a calf injury during the 5 - 2 win over CSKA Moscow on Tuesday.

The injury will keep Silva out until the start of December. He is likely to miss five matches.

Silva has already missed three league games, including the Manchester derby, and a Champions League tie against Viktoria Plzen because of a previous injury.

The 27-year-old has made an impressive start to the season, scoring three goals in seven Premier League starts.
