Defensive crisis for City

Manchester City could have just three fit defenders for Saturday's Premier League crunch with Chelsea.After the 2-1 Carling Cup defeat at West Brom, boss Roberto Mancini revealed he is desperately short of defensive options for the visit of Carlo Ancelotti's men.Unless Micah Richards recovers from a hamstring injury that kept him out at The Hawthorns, Mancini will have only Pablo Zabaleta, Vincent Kompany and Kolo Toure available to face the only side left with a 100% record."We have big problems," he said."I hope Micah Richards can recover. If not I don't know who can play left-back."
