Manchester City manager Manuel Pellegrini has warned that it will be an "important mistake" if Samir Nasri isn't included in the France squad for this summer's World Cup.

Nasri scored the opening goal in City's 2-0 win over West Ham United this afternoon as the Sky Blues picked up the result they needed to clinch their second league title in the space of three years.

However, the 26-year-old's place on the plane to Brazil is in doubt after he was left out of the last France squad by manager Didier Deschamps, and Pellegrini believes that Les Bleus would regret it if they ignored the midfielder.

"The manager of France hasn't said about the list, but I can't believe Samir Nasri won't be in it because he was one of the best players in the Premier League and very important for our squad," Pellegrini is quoted as saying by PA.

"It will be an important mistake if he doesn't play in the World Cup."

Nasri has amassed 41 caps for France since making his debut in 2007.
