To me, he shouldn't even be playing as a 6 because that just restricts him. He's a pure B2B midfielder and hasn't really been allowed to do such. It was a good game from him, honestly. You clearly haven't watched him for the youth team at all... Give him some time. This is the kid's second PL game and he's still playing within himself, so imagine a confident RLC strutting his usual stuff? The through ball to Costa was fine btw, linesman made a mistake. I think apart from his ball to Hazard, he didn't give the ball away. Give him some time to feel comfortable. Commentators even thought he was superb. He had three or four dribbles in the game that was more like the usual Loftus-Cheek. I'm waiting for him to get more game time and get more confident, and get used to PL football a bit more. He's coming along nicely.
