The challenge for him is how he will do when his confidence will dip. Right now, he's soaring, he's doing fancy things that all come through beautifully.
Send him back to Bayern for a 6 month loan if that happens.
He's found his home on the pitch. To what extent is that because of Ronald Koeman? That is the question.
I hope the missed goal scoring opportunities don't affect his confidence. That's his Achilles heel.
