Get him a loan to a team with a manager like Nagelsmann in the way Arsenal did with Reiss Nelson
Would make a lot of sense, we tend to have problems with loans though.
Look at Mbappe and the way he exploded into the scene at Monaco, and Sancho at Dortmund, he needs to have that faith out in him, a loan doesn't really do that, he needs to have a manager throw him in the deep end and see if he can show his skills.
There's no point wrapping a young player up in case it ruins his confidence, if it does, then he won't make it here anyway, some people are just not cut out for the too, he needs to be given a chance to show that he's mentally tough enough too.
