I really think he should be converted into a LWB to be played against weaker opponents. He runs for days, he's better receiving the ball in space, he's not an especially creative passer or good on the turn. However he's fast, he's dangerous arriving late in an attack, and he's effective when his starting position is wide. He has an excellent cross in him. His attitude to defending is excellent, and he knows how to tackle. Doesn't know his defensive positioning but has never really needed to before, and at 20 he can certainly learn.
In a team containing Bruno, Amad, Mount, Zirkzee, Mainoo and Eriksen there's no sense whatsoever playing him as one of the #10s. But I'm also sick of seeing Dalot struggling out of position at LWB after his year and a half of consistency under ETH on the right, where he should now be a strong back-up to Mazraoui. Garnacho would give teams so much more to think about as LWB.
