Really ?
I cant think of one thing Holla is better at than Stephens
Stephens is faster, more mobile, gets around the pitch, a better tackler, drives forward, better in the air, will score more goals, his passing is good short or long, and has some tricks when required,a proper box to box...
Holla and Kemy are the 2 central midfielders I would be looking to move on over the summer.
Kayal, Ince, Stephens, JFC and Crofts plus 1 replacement should be ample in that area.
