He told Chelsea's website: "At the moment [Nkunku] is coming back from injury. His best position is more like a 10 or a nine, more than the left or right side like a winger. To cope with the demands of the Premier League and what the team needs, it’s better in these positions. He is now starting to understand the Premier League, that teams are very aggressive and the football is very different to other countries. It’s good for him, more minutes. He will adapt little by little, but scoring will help him adapt quicker."
