Serbia coach Dragan Stojkovic is confident Dusan Vlahovic will come good for Juventus.
After an exciting start following his January arrival from Fiorentina, Vlahovic has struggled for goals in recent games.
Stojkovic told Tuttosport: "(Max) Allegri's game does not penalise him. Often the coach is criticised but for me he is one of the best in the world.
"Dusan has to find balance but he is already doing a lot. There is great pressure on him because they paid 70 million euros, but we must not forget that he is only 22 years old.
"He has the head and professionalism of thirty years old, not someone in their twenties."
