The striker arrived this month from Atletico Madrid.
"It is easy to see a big, strong guy using his body, attacking spaces, holding up the ball and pressing people," Mourinho says. "But, with proper football eyes, the guy is much more than that. The movement is incredible, the intelligence is amazing, the choices he makes in terms of movement are fantastic.
"The guy is a real top striker. I can say that because I’ve known him for a long time. Even the older players with us — Ivanovic, Terry — they say it’s fantastic that he’s coming because he is so strong.
"They say he is good in the air but, after three or four days of training, they change their opinion. They say he is much better than that. They thought about his physical presence, but he is much more than that."
