Former Manchester City defender Micah Richards says they need a radical change at the back.
Richards feels that manager Pep Guardiola must select centre-back options with more pace in light of Aymeric Laporte's injury.
Nicolas Otamendi and Fernandinho were the options for City in defeat to Wolves on Sunday but both struggled as they were outpaced on the break, with Richards suggesting that Kyle Walker is the answer.
"It will be interesting to see if he brings Kyle Walker into the centre-back role only because I watched the game and Man City had a lot of the ball but on the counter attack Wolves looked very dangerous," Richards told the BBC Radio 5 Live Monday Night Club.
"If the centre-backs haven't got pace you are going to get exposed. Maybe bringing Walker across just with his pace could be an option."
