Is he? I've yet to see it to be honest. In any case he's already behind Saka/Martinelli/Auba/Pepe in the wide positions who will all likely be here next season. I don't see a route for him into the first team on that basis.
He needs to play football on a regular basis for his own development.
I dont disagree with the loan argument, they all should go, the other two even permanent now, if there's a proper offer.
Yes, Reiss could regain his confidence on a loan, obviously he might also not but in any case should at least fetch an acceptable fee
Reiss being dubbed the best talent at many stages of his career is no fluke and those things dont disappear into thin air, he's definitely highly talented - even though, imo on that same position that ESR holds now.
Reiss was absolutely killing it at Hoffenheim and looked like Sancho, but he's lost his mojo with injuries and too many actions as super sub thereafter.
Also under Arteta, it's been mainly injuries sprinkled in
