The agent of Udinese midfielder Allan has revealed contact with Zenit St Petersburg.

Fernando de Paula says they're waiting to receive a concrete offer from Zenit.

"Zenit are very active on Allan and will soon begin talks with Udinese for the player. Much will depend on how much the Russian club will be willing to put on the plate to convince Udinese to surrender the boy," De Paula told Izvestia.

"He is very happy in Udine and Udinese."
