Man Utd legend Keane: Man City will be gunning for Fergie's lot
Keane reckons Manchester United would be out for revenge if they were to face neighbours City in the semi.
But they have to beat Chelsea in a replay first following their 2-2 draw at Old Trafford yesterday.
Keano said: "United are seeking a little bit of revenge for City winning a couple of years back.
"It gave City that impetus and their first trophy in a long time."
