Think Solsjaer would be a fantastic coup, he will manage United one day!
Everyone that has spent any time around him says he has a thirst for knowledge and a real desire to learn new things. Added to that, the hunger to succeed that United instills in all of their players, and he could well flourish at Villa. I really hope they make him a long term project though, he will need that time to learn, it's a big step up with immense pressures.
Hopefully he'll do well, and maybe loan a few youngsters from United to bolster their ranks - I'd much prefer Fabio to have a season at Villa than move to Benfica.
