Apart from Ulloa, I doubt if the others are very realistic possibilities, for various reasons.
But, I would add Hal Robson Kanu to that list , in style, he is like for like with Keinan, he has been a proven success at this level, and, with the Stripey´s getting a new Manager as well as, probably, new signings, he may be available.
The fact that his wife is a former Lingerie Model , has no bearing on my opinion , at all !.........Godzvilla!
