Udinese striker Antonio di Natale feels teammate Alexis Sanchez can become the best player in the world.

Sanchez was again on the mark in victory over Cagliari.

Di Natale said: "He will definitely become [the world No 1]."

Asked how much he believes they are worth as a partnership, he replied: "My price is that of Udinese, by now I am part of the club.

"Alexis will soon become the No 1. In a couple of years he will be fundamental for all teams."
