I have heard of beginners luck but really? Why are they even bothering looking at anyone else to take on the job? You don't need a big name to manage, you just need a intelligent person. SAF was not that flash a name at Aberdeen when he then arrived at United, but he had the brains.Just make OGS's position permanent before you lose him.
What's that? 8 games in a row?
Alex Ferguson had achieved 100 times more than Solskjaer has before managing Man Utd. Was already extremely highly regarded, and it was just a case of which 'big club' he'd end up in.
