Udinese director of sport Cristiano Giaretta admits several of their stars will be sold this summer.

Silvan Widmer and Allan are likely to leave, says Giaretta.

"Inter probed [for Allan] last summer, as [sporting director Piero] Ausilio holds the player in high regard, but I think a transfer this year may be a bit premature," Giaretta told Sportitalia.

"It's his third year in Serie A, he is consolidating his achievements at the highest levels and he is very dynamic.

"He is definitely ready for a great team, but we'll sit around a table at the end of the year to negotiate with someone.

"As for Widmer, we've had a few phone calls and he's doing very well. He is destined to play in an important team, but we'll see whether that starts this summer or whether he'll stay another year in Udine.

"Allan at €15m, Widmer at €12-13m, and [Thomas] Heurtaux at €11m? That's not bad as a starting point to evaluate them, but the price of a player is determined by demand.

"It's hard to quote a price right now. We have our own ideas but it's going to depend on the buyer."
