Hunter's pretty much nailed it, as usual:
Also, surely the best way we can play at present (heeding Sigurdsson's words) is:
Mirallas/Lennon Gylfi Lookman
DCL to come off the bench with Niasse and Vlasic?
Lookman has appeared inconsistent in his sporadic appearences, but no worse than Mirallas, and without game time he won't progress (until he fucks off to Spurs and becomes a world-beater).
