Goncalo Paciencia can understand major clubs watching Eintracht Frankfurt teammate Luka Jovic.
On-loan from Benfica, Jovic has been a revelation this and the striker's form has attracted major interest from Barcelona and PSG.
Paciencia told A Bola: "Jovic is a phenomenon, he's an ace, he has extraordinary quality. There are not many players like him. He will leave at the end of the season and he will be an elite striker.
"He is very strong, very fast and in front of goal, he is special. It is a privilege to be with him every day, to learn and enjoy what he does.
"Today, he is more mature and he has more experience, he explodes, and I am not surprised that Barcelona wants to pay 60 million euros for him. Given today's prices, paying 60 million for Jovic is not crazy."
