That was one of 2 or 3 things that I wasn't sure if he had or thought he could improve, his heading. Though he's won plenty of aerial battles in the prem so far, he just hasn't really had any chances on his head. Took it brilliantly though.
Think he can improve on his shooting from range and his passing, he's brilliant at just about everything else. He hasn't shot from range too much, but the few times he has they weren't too convincing. That's something that can definitely be improved upon though. As for his passing, it seems like it's just inconsistent which is absolutely normal for a young player. It's crazy to see how complete of a player he is at the age of 19 years though. Shrugged off a disappointing first half (a big part of it was due to Rojo not offering any support and CSKA doubling up on him and diving in every time he touched the ball), scored the goal and was a lot better overall in the second, especially with added support from his fullbacks instead of being isolated 1 v 2 at all times.
