Former Manchester City midfielder Patrick Vieira expects his old team to be too strong for Manchester United on Wednesday.
City are two points behind leaders Liverpool with a game in hand.
Nice coach Vieira told Sky Sports: "It's a derby, and it's always difficult to play a derby, but I think City in the last couple of years has been the best team in Manchester.
"I hope they will manage to go to the end and win it because they have been really consistent. They have been playing some fantastic football.
"I really enjoy watching them every weekend, they are scoring goals, and I wish them all the best."
