If circumstances were different then Uche would be a no-brainer of a signing. He has lots of raw ingredients, is still young, and is not so expensive that it would sink us if he didn't make it.
Thing is, we have committed very large sums to Nketiah, Larsen, and Johnson, all of whom were supposedly 'proven' but none of whom have yet done as well as required (though Larsen is doing OK). We couldn't possibly hope to sell any of them at the moment, at least not for anything close to what we paid, so they will stay and we simply must get a tune out of them. They must play, at least at the outset.
We have also spent good money on Pino, who is starting to look a tiny bit brighter, but that's probably just because he has been so bad that when he does anything good we all get excited. We have yet to recoup anything on Franca and probably won't. Esse has gone on loan to get games but yet the jury remains out. That's a lot of money spent already on 'unproven but exciting prospects'. If the new manager thinks to look down the back of the sofa he might find Rak-Sakyi, who remains under contract with us and is perhaps the best our academy has produced in recent years. That's four players who might very loosely be described as possessing potential, and about £50m in fees spent. Will we just write them all off? Surely at least one or two must be part of the first team squad next year?
Sarr is our best player and must be a fixture in the XI. We are presuming that Mateta will be sold, but he's already failed one medical so who is to say that he won't be here next year, even if nobody involved wants that?
I just can't see a space either in the squad or the balance sheet for an outside bet like Uche. Much the same is true of Guessand, who has shown flashes of exciting play but only in amongst long periods of dross.
