No, you`re not. Sergej seems like a player with great potential, but he is so far away from being an established and top notch player his price tag suggests. He still hasnt accomplished anything remarkable, so far he`s one of the leaders and top performers of the 5th placed team in Serie A, even a 100 mil is way above his actual price.
Wait for the Serbia`s exit from the World cup, then if he publicly say he wants out of Lazio and tries to push his way towards team A, B, C or D, Lotito will lower his absurd demands, he would be an absolute dumbazz to repeat the Ledesma, Pandev and De Silvestri scenarios. But he actually is a dumbazz so who knows...
