My country is a neighbour of Serbia so I really have watched a lot of games from their players and one of them who always really impressed me is Kostić. He is faking beast on left side because of his incredible lung capacity so he can run whole game up-down, up-down etc. His position are on left side from AML to DL but actually he isn't best on left back coz defensive lackiness (same as Cuadrado), but for our rotation he will do amazing job if he of course signs a contract. Bonus is his healthy, physical condition and shape, what is totally different situation with a lot of our clown players which are made of paper with chronical pain in penis for playing games.
