We do need a bit of bulk, but at the top end we're talking about having:
Oscar, Tetteh, Delap, Connelly, Traore, Tufan, New Number 10 (Twine?), Lokilo, New Winger (Philogene?), Allahyar, Vaughan, Longman.
That's ignoring Sinik, Jarvis and Covil who I don't see getting significant game time. It's still 12 players for 4 spots on the pitch. Depth is one thing but that seems excessive. So I'd definitely expect a few to go if we get all these players in. Maybe add Longman to the list of possible outs.
Combination of championship schedule, injuries and the new sub rules means its probably about right. Especially when 2 of those mentioned have a bit of an injury history
