Gotta call him slimey since it effects us, but I actually respect his professional attitude and focus on solely furthering his own career. Even to the point of apparently taking a pay cut to join us or even being willing ditch his country for England if it meant a chance of going to the World Cup.
But that's also precisely the problem with him getting the Arsenal job since romanticism seems to be the sole reason people are fine with him getting the job.
What's the point in giving him his start and apparently the couple of seasons we need to be patient with him so he can learn on the job, when it's safe to assume in 2-3 season if he is any good Barca will come calling and he'd be off?
Arteta is very far from my first choice, but I don't think the people who do want him do so for romantic reasons. Nobody is under the impression he's a legend in the vein of Henry or Vieira. Most likely they want him because of how highly regarded he is and the fact that he appears to demonstrate very promising signs of being a good coach. It just so happens that he also played here and knows the club.
As for the point that he may go to Barca in the future, well who wouldn't? Very few. If someone is getting a job offer from Barca then it means they've done some good things, which can only mean that he's done a good job here. That's a good thing surely. Wenger is an exception, most people will step up the ladder if given the opportunity, managers just like players. Barca is a step up, whether you like it or not.
