Manchester City new boy Samir Nasri claims a lack of transfer activity at Arsenal convinced him that the time was right to move.
The France international completed a switch to the Etihad Stadium on Wednesday, following a summer of speculation regarding his future.
Nasri made it clear early on that he was looking to make a fresh start, with contract talks shelved at Arsenal.
He is delighted to have joined a forward-thinking club, and one that can match his ambition.
The 24-year-old admits that he was left questioning his future and that of the Gunners towards the end of his stay at Emirates Stadium, and believes he had no choice but to look elsewhere.
Nasri told L'Equipe: "Why did I not sign a new contract with Arsenal? We started talking in October but by June I did not have any news and I didn't see anything happening in the transfer market. There comes a time when you have to invest.
"I have heard people say I have moved for money. I make a good living at City, that is true, but I am 24 years old and I have reached a turning point in my career and it was important that I joined a club with ambition.
"I believe I have more chance of winning titles at Manchester City than at Arsenal."
Nasri added: "When did I make my decision? Early in July, when we returned for pre-season. I told the coach (Arsene Wenger) that I wanted to leave.
"Is it a risk joining Manchester City? You have to take risks in life. I am not afraid to do so.
"There is a big squad here but competition is good, it makes you push yourself and stops you from becoming stale.
"Was that the case at Arsenal? Maybe."
