Manchester City midfielder Samir Nasri has said he thinks Chelsea currently look invincible at the top of the Premier League table.
Nasri, who started for champions City in Saturday's hard-fought 2-1 win over Swansea at the Etihad Stadium, told the Manchester Evening News that had been a vital victory for his team.
"It was important to keep in touch with Chelsea, who look unbeatable at the moment," he said. "It was really important to win the game."
City fell behind to a Wilfried Bony strike within two minutes, but goals from Stevan Jovetic and Yaya Toure secured the three points for Manuel Pellegrini's side.
"It was a tough start," Nasri said. "They scored an early goal, but we had a good reaction. We started to press high and play our game."
With Tuesday's Champions League clash against Bayern Munich looming large and a disappointing run of only one win in six games, Nasri said: "It was good for the confidence as well, because on Tuesday we have a tough game.
"We are really lucky to be in with a chance of qualifying because, with two points and two games left, normally you are out.
"Now is our chance. We have to take it and play with nothing to lose. We can take a lot [from this win], but a game against Bayern Munich will not be the same as against Swansea.
"No disrespect to Swansea, who are a great team, but Bayern Munich have world-class players in every position."
Pellegrini previously set his team a challenge of taking at least 22 points from their next eight league games in order to reach the halfway point of the Premier League season in a position to challenge Chelsea for the title.
