The problem is more to do with the lack of trophies, or at least the lack of progression. There's no difference between Arsenal football club now and how we were 5 years ago. It's just an endless cycle of scraping top 4, getting nowhere near trophies, selling off our best players and then spending next to nothing on replacements. It's only natural that a player with about 10 years of top level football in him, would want a change of scenery to a club with real ambition.
