Apparently, Klaassen has played as a false nine before.
It would be nice to see him again, in some central role. I'm seriously disappointed at how Unsworth has frozen out so many of our summer signings.
I think to some degree up until this point I can give him some slack. When you're in a crisis of sorts, or just finding your feet it's understandable to go to known quantities. He should be talking to those players he has frozen out though during that time, letting them know what the deal is.
However, I feel that immediate finding his feet period has passed with the international break giving him more chance to familiarize himself with the new players. If they continue to all be left out en masse I'd be very disappointed. I think as Niasse has shown, all these players should be able to contribute something if coached/utilized properly in a balanced team.
