ABIDJAN: Ivory Coast's African Player of the Year Yaya Toure is doubtful for their opening World Cup group game with Japan on Saturday, coach Sabri Lamouchi told the Ivorian press on Tuesday.

The 31-year-old Manchester City star -- whose performances and 20 goals for his club last season were instrumental in bringing them the Premier League title -- is still struggling with a hamstring injury he suffered in the title deciding win over West Ham on the last day of the league season.
