I'd love Draxler, now wouldn't be the time to throw him into the deep end as a striker though. We'd be overstocked on left wingers too.
Think we realistically have to go for a striker in order to replace Theo's output, and play Gnabry and Chambo on the right wing.
Alternatively, Carlos Vela wouldn't be a bad option. We allegedly have a very cheap buy back clause, and he can play both RW and CF.
