City have won 13 of their last 14 matches in all competitions including their last seven matches in the Premier League.
Meanwhile, we've won seven, drawn two and lost just one of our last 10 games in the Premier League since the last time we met City at the Etihad in November - no-one will need reminding of the scoreline that day...
"I didn't play in the game at City but I watched it on the TV and I felt for the guys," said Christian, who was recovering from an ankle injury at the time.
"Hopefully we can put it right now. You can feel that now the game is getting closer. Everyone wants to be 110 per cent for this game.
"Everyone knows you have to be on your toes when you play City. You don't even have to say it. We have to be at our top level and that's what we want to achieve in this game."
