Micah Richards, Yaya Toure fitness doubts for Manchester City

Manchester City have fitness doubts over Micah Richards and Yaya Toure ahead of next Monday's derby encounter against Manchester United.

England international Richards is currently struggling with a hamstring injury that forced him to miss Sunday's 2-0 win over Wolverhampton Wanderers.

Meanwhile, midfielder Toure is believed to be struggling with a muscular problem in his leg.

Should the duo recover to be available for selection, manager Roberto Mancini is expected to have a fully fit squad at his disposal.
