Mourinho has been impressed by what he has seen during the pre-season games. Do not be surprised if Van Ginkel features against Hull on Sunday.
"Van Ginkel has an engine," said the Chelsea manager. "He has physical power which is not normal for such a young kid.
"He covers a fantastic area of the field defensively and after that he has this instinct where he wants to go into finishing areas, he wants to score goals. He's very good in the air.
"He has to learn tactically and even technically, he has the space for improvement, but potentially the kid is very much adapted to the Premier League."
