Having 4 senior midfielders and 1 high end youth player as back up is hardly going into the realms of a bloated squad though is it?
As i said there is the league cup and FA cup to consider as well as the additional subs rule.
I mean it's a bit of a fantasy, but if we are 2, or 3-0 up in a game he could come on then too for a bit of experience.
Also we've seen many players go out on loan and not get played properly, they can fall out of favour, be played in their wrong position or just simply hate it and not perform.
