Rather than just picking names, isn't it better to identify where the main needs are, and then decide whether those names being mooted fit the identified need? Just because a player may be good, doesn't men they meet a need. Or is that too sensible?
We want imho
1. Firepower up front - which crudely speaking can come in one of two guises - a big target guy or a poacher finisher. As we often play one up front with O'Hara playing off him, the former is the big missing - a classic, large, athletic, front man - Baka only a lot more physical.
2. Defensive midfield - a temporary Kelly replacement - difficult as that position is usually best occupied by an experienced head, rather than a classic loan.
I don't know enough about either Crowley or Clarke but on the face of it neither fits the brief. It is possible that Cowley could take Sheaf's place, as he has been too inconsistent, but that would still leave these two big gaps unfilled.
We should not panic. We're 17th on p.p.g. with one of the tightest Championship defences despite an inexperienced second string goalkeeper. In the summer we will have Hamer money....
