Liverpool legend Graeme Souness says Manchester United will beat Manchester City on Saturday.
As well as home advantage United have another key factor in their favour with City's main man Sergio Aguero set to miss the game through suspension.
Souness told talkSPORT: "I think Man United at home will edge it.
"City, I'm not sure if all the players are grasping want the manager wants right now - that might take a bit of time.
"I'm just thinking the firepower Man United have might be the difference.
"And [Sergio] Aguero not being there – he is a worldy for City and when he doesn't play the stats are very different."
