He had only one good season where most of his goals came from the bench, scoring in dead games. While his performance in Juventus was average for a striker scoring only 8 goals. He is 24 years and there is nothing special about him, usually brilliant talents shine already at age 18 and 19 like Rooney, Ronaldo, Mbape and many others. But for him, to hit 24 years and still a substitute is nothing impressive. I am not saying he is not going to turn out to be a great player, but signing him for that big money is a huge risk on someone who has a very high failure rate than the other world class strikers.
