Yes, but that's not the issue here.
I just think on the face of it we could be quite blase about the CM options.
But looking beyond the quantity and appearances the only man for man replacement is Crofts.
That's why in answer to the OP's claim 'I wouldn't have thought we need anymore...
Have any of them been used in the 4-4-2 system?
Ince is definitely Mr 4-5-1, the Rumbelows Cup formation.
JFC replaced Stephens at Fulham inside the last 5 minutes, and sadly it'll be a brave manager who relies on Crofts.
If CH has no confidence in his current back ups in a 4-4-2 formation (Ince, JFC, Crofts, Holla) the club desperately needs back up, and very very soon.
