If we get Rashford, Garna, Sancho out the door and assuming we don't bring in any more fullbacks I think we could do a lot worse than keeping him as a WB rotation option.
For his all his many faults he is a hard worker in his defensive work. Could fill in as a 10 if we hit an injury crisis.
Even if he doesn't play we aren't exactly swamped with good offers atm
His stock is never been more higher. Betis are seriously interested, he loves it there. Now it's the time to sell him, providing somewhat of a good offer comes in.
