Shaw has qualities and will be here next season unless someone's prepared to give us back what we paid for him...
I doubt anybody would pay £30M for Shaw. £15M-£20M would be about right.
Although he isn't particularly good (contrary to what MUFC fans stated, who saw him as the best LB in the World), he is still young, so may yet improve to be decent.
I don't ever expect him to be a top LB, but for a mid-bottom EPL team, I think he can be a first team regular. His injury situation is worrying, though; in 3 seasons, he has played very few games for us, which is bad luck, I guess.
Given our problems with injured defenders, I'd much rather we bring in a LB who is in his absolute prime. In 3 seasons, we have never been able to rely on Shaw and it would be folly to expect him to play any more than 15 league games per season. He may though, be used as a squad player to give our No.1 LB, a rest.
