Thought he was kinda sloppy and his problem is the same as Arthur's, he doesn't know his best positioning yet. Lacks fluidity. As a workhorse did well though.
For the next few games, I'd start Vidal, Busquets and Coutinho. We need the solidity that Rakitic is not giving us at the moment.
Paulinho 2.0 will help us kick start our campaign. Plus I think he'd give the freedom for Coutinho to combine more with Messi, which is just about the only thing we've got going for us so far this season.
