My initial thoughts were, and still are, that this is a sensible deal.
Comparsons can be drawn between Nouble and Balotelli; unquestionably both have genuine talent and potential (albeit different scales), but there are big questions regarding their commitment, temprement and laziness.
For those reasons, the jury is still out on Nouble with the majority of fans, evidently with Pressley too.
Granted there is is a risk with a four month contract but this can be offset against the risk of offering a player of this mould, and more importantly wage structure, a longer deal. If he plays well, we get the benefit of that for the reminder of the season, if he then gets snatched away it will be disappointing but he is replaceable. Plus who knows he may go against the trend of modern footballers and show some loyalty.
It is different from extending the loan, as already pointed out, it allows an extra loan player in both the squad overall and the match day squad. Loans are not ideal but if we get a player that makes the same impact as McGoldrick, I doubt there will be people moaning about the number of loan then.
