Zero chance of him coming back here, what is more likely is they offload him to a club who will play him as a no 10 for a similar price. That's not likely either, as they basically will want to keep him as a backup 10 for Berghuis, and also for Brobbey, and just fit him in elsewhere until they need that.
He's had 30 minutes up front (away) and 60 minutes on the right wing (away), considering the only season he's had real success (which was massive) was as a 10, then it kind of makes sense to expect him to only perform as a 10. You're not going to get much out of him elsewhere, certainly not initially. To write him off, like how El Ahmadi has is stupid.
They will gain absolutely zero form him going out on loan, to anyone, other than losing strength in depth, which they will be keen to avoid.
