I actually disagree there Southern Muppet. Nasri received a lot of abuse and made comments which caused Arsenal supporters to rise to it and establish their hatred for him.
Because of Van Persie's contributions to Arsenal I don't think they will dish out the same animosity as they did with Nasri. Robin chose his words very carefully when he stated that he wasn't going to renew his contract in order to avoid conflict so I don't foresee a problem between the Arsenal supporters and Van Persie.
They cannot begrudge him a move to a club where he is more confident of gaining medals and lifting trophies before he retires. This will potentially be his last large move before he does so and to stick with a club that has already not achieved anything in seven years is to show a lack of ambition and living in your comfort zone.
He could do a U-turn and retire an Arsenal legend. That would be the easiest option, but for him to move on so he can win things tells you about his personality and mindset.
