Samir Nasri's last two games could not have been more different. A week ago he was floundering in a depleted Arsenal side losing 2-0 at home to Liverpool. This unhappy experience was his last game for the Gunners, as he clinched a move to big spending Manchester City days later.
This weekend he slotted seamlessly into the Man City side, creating goals for striker Edin Dzeko as they dismantled Spurs.
It underlined the sporting reasons why he would want to move to Man City.
City are a team with an unlimited future, a real-life fantasy football team, while Arsenal are a team seemingly in the midst of a hurtling decline. Yes City have the power to attract players for financial reasons, but the majority are there because of the footballing project, because they believe the team is the place to be.
If you were Samir Nasri would you rather play in midfield with Emmanuel Frimpong and Alex Song or David Silva and Yaya Toure?
City have a strong chance of winning the Premier League and many will fancy them to progress in the Champions League further than Arsenal. Nasri clearly spoke with former teammate Fabregas and on finding out he was off, made up his mind about the club's ambitions.
Arsenal cashed in on him, many would argue too late.
If Arsenal had signed proven midfielders early this summer, they could have inspired Nasri to stay. Instead his departure only highlights how a young ambitious player has lost faith in the Arsenal project.
Wenger has a lot of work to do to convince potential signings that success can be achieved, and from this point on lies his greatest challenge.
But if any Arsenal fans still think Samir Nasri is purely a money grabbing mercenary, they are wrong, he just wanted to leave a team on a downward spiral to play for a team which is going places.
