He can play centre midfield and can also play in defence too. With the current trend of teams opting for three at the back and Koeman also using this formation it may be useful to use him as one of the back three. He has more pace than some of our defenders and would cope better when having to defend against quicker players running the channels.
I really think there's a good player there, it's a shame he has had so many injuries that has held him back a little, I really hope he has an opportunity this season and is free from any further injuries, he deserves some luck.
