A pretty good transfer for them for 40-45m. He's underrated. Yes he might shoot wildly at times, but he's one of the most creative midfielders out there that can play out wide and fit into the midfield as an attacking CM, and he works his ass off.
Now we'll probably need to find another club to ship Coutinho to. In the end it might come to down to a Coutinho + cash deal for Neymar if no one else is interested in a straight transfer.
