Manchester City boss Roberto Mancini believes that his players need to treat every game like a Champions League final.
The North West club are leading the Premier League title race by two points and could extend their lead to five before rivals Manchester United take to the field on Sunday.
City are preparing to go up against Blackburn Rovers tomorrow.
"It is impossible to be complacent," said Mancini. "Every game is like a Champions League final and for this reason we need good concentration.
"Now we have a game against Blackburn on Saturday and I think every game from now until the end will be difficult.
"When you play against a squad playing against relegation, it can be more difficult. Blackburn won away against Manchester United and we know they are a good team, they are strong on the counter-attack."
Mancini's side have 13 games left to maintain their place at the top of the table.
