It doesn't seem the dead wood will be leaving this summer. No rumours of anyone interested in the likes of Pienaar, Kone, etc. If RM has a bounce back this season and isn't sacked, next offseason will be a massive one. Maybe that's why he's saving the pennies this transfer window? Here's who's contracts up 2016.
Hibbert
Gibson
Oviedo
Kone
Mirallas
Osman
Pienaar
Stanek and various other youngsters
A lot of dead wood there, but also Mirallas, Osman, Kone will be expensive to replace with quality, we don't really have any youngsters able to take those roles yet. I expect Ledson to take over for Gibson on the roster, but that's about it.
