Shame.
He is completely two footed, can tackle, has a good eye for a pass and is a good communicator on the pitch.
I don't really know what to see to people who can't see what he can bring to a side.
I understand those wary of him staying fit long enough to do anything but his actual ability should be obvious.
As for where he could fit in, Besic, Schniederlin and Gana as 3 midfield destroyers who can also go anywhere and pass the ball would work for me. They are all intelligent players who can switch position with each other.
It's the future. Davies and McCarthy (to an extent) can do it too.
