Harry Redknapp insists we'll have to be at our best to topple Wigan at the DW Stadium on Saturday.
The Latics are fighting for their lives at the bottom of the Premier League.
But they impressed recently in a narrow loss at City before a come-from-behind victory against Birmingham City last time out.
We travel north on the back of decent performances against Wolves and West Ham, but with only two points to show after a 3-3 and 0-0 draw respectively.
Those results see us fifth in the Premier League, four points behind City with a game in hand.
"I like Roberto Martinez, I think he's a fantastic young manager, always positive. I like the way he tries to get his teams to play," said Harry.
"They are in there scrapping. It will be a tight run-in for them but they had a big win against Birmingham and they are dangerous. We'll have to be at our best to go and get the win we need.
"There are no easy games. That's why it's the best league. It's tight at the top, I think the title race is still wide open and it will be an amazing end to the season at the bottom.
"The lads are focused, they know how important it is for us to try and make that top four again.
"We've worked hard all season for it. We've been fighting on both fronts and never let the league go, we've been in the top four or five all season.
"It's an exciting end to the season. Real Madrid, Chelsea, Arsenal, City - massive games. This is why we're in football, to play in these big games."
