We won't be able to sell Ozil with his wages and even if we somehow did it would be at a loss, Ramsey is worth nothing now, Lacazette I'd keep, he's one of the positives player wise this season, with him in the team we seem to have more threat.
It would help wages of course, but we probably won't give Emery much money either, we're not that kind of club and he's got noone like Coutinho to sell to raise funds either, tough job, but then it was always going to be as we were left in a real mess.
