Don't want Alli about the place. His work ethic and attitude are toxic and, for all his talent, he fits the system and style in Spurs much better where he can laze around and leach off Harry Kane. Isco is a far better option here on every level.
As for the Ox, he actually does put in a shift and his effort is in line with requirements under Guardiola. So does Delph though, so obviously effort isn't everything. IMO, Ox would be good squad depth but never a first team starter. If he's happy enough playing that role, as he's done at Arsenal, and he's not outrageously expensive, then why not?
