Best time to sell, I reckon - we require a major upgrade in personnel in certain areas right now to either convince our brightest talents to stay, or else manage reasonably well without them, and players like Shelvey just cannot be afforded the space and painstaking patience to grow into the footballer they may or may not become, in this particular team at this particular juncture.
I've grown fond of Jonjo, I'll defo miss him in a way and I certainly wish him all the best, but he's proven a far more frustrating prospect than the likes of Henderson, Sterling, and Suso, for me. They haven't exactly cleaved the world in two with their prodigious genius either, but I'd come to be almost always expecting Jonjo to do something utterly lame-brained pretty much immediately after showing a brief glimpse of a special talent. Maybe it's a little unfair on a young lad still with such potential, but I hope he can improve his concentration levels and push on elsewhere.
Only a good decision on our part if we bring in that significant upgrade, mind. This window is on a proper knife-edge for us, if you ask me - all these astute, promising early dealings could turn to absolute shit so easily if we're not equal-parts careful and bold.
