He was in and out (mostly out) of the starting XI last season. He comes off the bench every once in a while.
Tigana isn't too keen on using wing midfielders, which is to Bjarne's disadvantage. And I think he's lost a step. Although at the same time, he can be useful in bringing a new dimension to the team when brought on as a sub.
I personally find him more useful than Tigana seems to.
