I don’t think the ambush on Manchester City’s team coach affected them — despite their complaints after the game. If anything, it should have made them more determined. They are all top-class players and have performed in intimidating atmospheres before.
David Silva and Vincent Kompany have been involved in plenty of Manchester derbies over the years and they would have passed on their experience to the younger players.
We went through a similar thing at Arsenal when Sol Campbell returned to White Hart Lane after his free transfer across north London in 2001. Tottenham fans pelted our bus with stones and bottles and screamed abuse, but it readied us for the game.
