I think this is a brilliant move for him. He's likely to start every game and I can see him forming a decent partnership with Knockaert. He needs a team who will try get the ball into the box quicker rather than focus on build-up play (like ourselves). I can't see him returning to us however as I think Llorente will prove to be a success.
I can understand - given that this seemed to happen at the last minute, and may have caught him off guard - but he will struggle for minutes here - and that may impact his standing on the national team.
It reminds me of when Pritchard chose WBA rather than where Poch supposedly wanted him to go. I envisioned Janssen going off on loan - scoring a few and then coming back as our second choice next season.
