Enzo Maresca’s in-form City head behind enemy lines on Sunday when we face Manchester United in a 16:30 (UK) kick-off.
Having won all three Premier League games so far as well as our Champions League opener in Porto on Tuesday night, Maresca’s team will be full of confidence going into this one.
But the manager and his players are well aware of the stakes of a local derby like this, where bragging rights go hand-in-hand with the three points.
However, there was a relaxed atmosphere in Manchester earlier today as the players gathered to go through their paces to ensure we’re in tip-top condition for the weekend.
