I'm really curious about his future. If he maintains this trajectory, he could cement himself at either CM or RB depending on our needs. We'll see how Vidal fits in the side when he joins and if he works out at RB well enough. If not, Roberto can make that position his home. Conversely, he could be the RCM support player like Rakitic has been. It makes a lot of sense given how he provides the same defensive cover and off the ball movement to support the right flank, along with his somewhat superior technique on the ball.
As great as his interplay and movement has been, there's always more to add and improve. I'd like to see him get a nice long range pass or more frequently utilize his good shot to really round himself off. Which spot would you guys prefer him at?
