Most of the players that have left Arsenal in the past, did it because they were not content with club or because Arsenal needed to raise money from their sale.
Sami Nasri left Arsenal in a controversial circumstance to join the Citizens in the summer of 2011.
The Frenchman went on to win two Premier League titles at City with Arsenal still waiting for their first since 2004.
And Nasri says the club’s financial stance has been a big reason for that.
“I do not know. I do not know why (they aren’t challenging),” he told French magazine Onze Mondial.
“We must also take into account the fact that when I was in Arsenal, we did not fight on equal terms with Chelsea or Manchester United.
“Arsenal made the choice to move to the Emirates Stadium, so there was the stadium credit.
“The bosses of the club have always wanted to have healthy finances, they never wanted to go into debt.
“So they obviously did not recruit like the others.
“Since I left, they have won two Cups. They are trophies and all trophies are good to take.”
