I always thought he was a wasted talent at Chelsea, really hope we can get the best out of him.
He has it all technically. I think the missing big chances is a mental/confidence thing that he can overcome.
Assume he is our new left 8 and would expect him to match Xhaka's output from that position (though a little worried about the defensive side).
He is used to the league, works hard out of possession, reliable in terms of availability and most importantly wants to be here.
I think he will do well and he will have our support all the way!
