Atalanta admit they face a battle to keep hold of Federico Peluso and Manolo Gabbiadini.
Peluso has caught the eye in defence for the Bergamo boys, while striker Gabbiadini is being tipped for big things.
"Almost all of the big clubs are interested in Peluso and Gabbiadini," said Atalanta technical director Pierpaolo Marino to SportItalia. "However, that doesn't mean we want to sell.
"Peluso has a left foot that few in the game possess, while there are no limits on what Gabbiadini can do.
"Just ask Italy Under-21 boss Ciro Ferrara who always plays him even when he doesn't find space in the Atalanta side.
"Will they move? When a player receives a call from a great team then it is always difficult to resist as was the case with Simone Padoin and Juventus in January."
