I doubt that it you exclude Bellerin from that list we'll get £50 million for the rest. It will free up about £250,000 a week since I assume Wilsher and Szcesny have their wages paid by the clubs they are loaned to.
Bellerin would be a loss, less of a loss if we use a back three but if we ever revert to a back four we wouldn't have a proper right back in our senior squad. I have to assume Debuchy and Jenkinson will be offloaded asap.
Jenkinson was last spotted playing a fortnight ago for the under-23's. West Ham stopped the loan when he got injured I think. Debuchy has also played for the reserves this season, I think he might be on a free at last which will be goodbye to him.
Just checked, Debuchy not on a free yet but apparently Leicester and Marseille want him.
