Colback is match fit ( ), Tiote's not.
Colback is a worthless turd of a human being at his very best. Tiote can be serviceable at times. Neither should be anywhere near this club.
Colback played well against Wolves midweek. Contributed to a few attacking moves, Tiote never contributes going forward.
Ronaldo is spot on, there's absolutely no need for Tiote at this level.
