Liverpool legend Jamie Carragher believes Kurt Zouma can be Chelsea's secret weapon against Manchester United.

Carragher believes Jose Mourinho will bring Zouma into his midfield to neutralise Marouane Fellaini.

"Jose Mourinho very rarely gets done tactically in a big game. His record is fantastic," Carragher said. "There's no doubt, he won't go in with just his normal set-up, he'll use something different. I'm convinced of it.

"I think there's a case for bringing Zouma into midfield, maybe get him on Fellaini, because Matic is left-footed and he won't want to put him on the right side of central midfield."
