Roberto Mancini frustrating Manchester City stars?

Tensions are reportedly high in the Manchester City dressing room due to manager Roberto Mancini's continuous tactical changes.

The Italian boss switched his side's defensive shape midway through the North West club's 3-1 defeat to Ajax in the Champions League on Wednesday, which caused full-back Micah Richards to reveal that the players are not keen on playing as a back three.

It is understood that a number of senior players are growing frustrated with the 47-year-old but the Italian coach is not thought to be under pressure from the owners and is expected to keep his job, according to the Irish Independent.

Mancini put pen to paper on a new five-year deal at the Etihad Stadium in July.
