Young coaches going straight into management at a young age and being successful are becoming increasingly more common.
He's learning from the very best and has an extremely good reputation within the game.
Seems like he's been tipped to be a great manager and he certainly has a good backround. He'll have that guardiola education, mixed with years of playing under David Moyes.
Also, we're basing ourselves on the model of having a head coach instead of a manager. Meaning all his attention would be towards drilling the players on the training ground whilst brands builds a team suited towards a style of play Arteta needs to succeed.
I'd personally love us to take a risk on him but obviously there's massive reservations and rightly so.
