Atalanta coach Gian Piero Gasperini was pleased with victory over Europa League opponents Rakow.
La Dea won 2-0 thanks to headers from Charles De Ketelaere and Ederson.
Gasperini said, De Ketelaere has some very similar characteristics to Josip, but he is still young and has great margin for improvement," Gasperini told Sky Sport Italia.
I am happy with his character and work-rate too. I heard people say he was a bit sluggish and indolent, but the truth I feel is that he has this muscular structure that means he needs to play regularly to get into shape. Sometimes the body language can make it look like laziness, whereas it's just trying to find that rhythm.
He has good feet, solid foundations, he played as a centre-forward in the second half and is versatile. In an emergency situation, he can also be a centre-forward, even if it's not quite his role, but it could become it.
Obviously, it would be a very different potential with Scamacca and Toure. At one stage tonight, we used Mario Pasalic upfront. Losing two players like that leaves us rather short-staffed in attack."
