He knows he won't be first choice next season, and chances are not the season after that either
Does he really want to wait 18 months before he gets a decent run in the side? He's young, he's good, he wants to play first team football. Can't blame him for that, and can't blame Everton for having England's first choice left back in the side - we'd be complaining if we didn't!
It's just one of them, as it seems good left-backs are like buses
I may be talking out of my arse here but surely any other club would have loaned him out to a Hull, Sunderland, West Ham type of team where he'd be more or less guaranteed first team football, especially considering Baines wont be a left back forever if we're to believe Martinez saying he'd like to use him like Lahm and play him centrally.
I'm sure there's a lot of stuff we don't know about Garbutt and the whole situation but from a fans point of view it's crazy we'd be letting this lad go on a free when it's clear he's got a big future ahead of him.
