Samir Nasri admits that he has at times found it hard to live up to his price tag since moving to Manchester City.

But, six months on, the Frenchman is adamant he made the right move, with City still top of the league.

And he believes his old club Arsenal are currently faltering because they do not know how to "win ugly".

"Sometimes it's good to win ugly," Nasri said. "Arsenal are proof of that. They play good football but, after seven years, they don't win."

Arsene Wenger's side have lost five of their last 10 matches, leaving them 17 points behind Premier League leaders City.

They trail AC Milan 4-0 after the first leg of their last-16 Champions League tie - having not won a trophy since the

Wenger has come in for criticism in the past week with former Arsenal and France World Cup-winning midfielder Emmanuel Petit saying this was "the worst moment of Arsene's career with Arsenal".

Former Gunners manager George Graham has also said the club is failing because Wenger has not bought "quality" players.

But Nasri is hopeful that they will get it right in north London.

"I don't want Arsenal to fall down," he said. "I have respect for the players and the manager.

"They have a good philosophy. I know they will find some solution."

Since moving to Manchester in the summer, for £24m, Nasri has started 25 matches for City and believes he is now starting to show the form that earned his big-money move.

"It's always tough when you change," he said. "When you go to another team and have to be involved 100% and I wasn't.

"Now I start to be settled and you will see a better Samir every week.

"I never asked City to pay £24m so it's not me.

"What you want to do is to give something to the team and the people who bring you here and trust you."
