Gillian showed he was a very limited 1 trick pony with no end product.
That is true, but in an abstract situation where this could be a thing to consider, I do not think we have currently a player like that in that age group. He is old enough to have sufficient physical strength, has good speed, but is young enough to have a potential to get better if coached correctly.
But as I said, not sure that A-FC would cut people just because they are not the first eleven. He is a decent backup (for A-FC), and if Sutton is replaced by LKH, Gillion may play further up.
Not clamouring for Gillion, just saying that with our squad gaps and our budget, one club's "also-rans" are another club's first team.
