What I like is that he is good at using his body to protect the ball. I look at somebody like Pulisic, he's a very good dribbler, but he's also very weak when it comes to protecting the ball, so it's really hard for him to run past players. The opposition find it too easy to place their body infront of him and the ball, so he just bounces off them and losses possession. In a 1v1 with a defender running straight at goal, I think Pulisic could be good, but those situations come around very rarely in the Premier League. Pulisic won't be running past defenders from a standing position, he just doesn't have the close control and strength to do it. I extend these types of issues to Ziyech, Havertz and Werner too and it's one of the main reasons why I didn't want us to sign Dembele.
This is what made Hazard so good, he was a world class dribbler but was also world class at shielding the ball. Nkunku and Hazard have the same build and dribbling style, they use their body to protect the ball and have close control dribbling. It's a combination that works really well in the Premier League is almost a requirement if you're going to play against teams that pack their defence, so fingers crossed that it works for Nkunku too if we sign him.
