Kolo Toure believes that Manchester City need to "stay cool" and keep focused on the club's remaining 11 games in the Premier League season.
Roberto Mancini's side currently sit two points clear of their bitter rivals Manchester United in the league table.
"Mentally we just need to focus on our game and play every game like it's a final," said Toure.
"It's going to get tougher and tougher, because it will get more intense, but we just need to keep our heads and stay cool.
"It's a mental test as much as a physical one, because you feel the pressure from the other teams and you want to deliver."
Man City switch their focus to the Europa League this week as they prepare to take on Sporting Lisbon on Thursday.
