Arsenal target Gokhan Inler could leave Udinese according to his agent, should the right price be offered for the playmaker.
Manager Arsene Wenger is a long-term admirer of the Swiss midfielder, yet could face competition for his signature from Napoli.
"Udinese are very attached to their players, and it feels like a real family," said Lamberti, according to the Daily Mirror.
"Should an offer arrive for Inler - and an accord be reached - [owner Giampaolo] Pozzo will let him go. During the summer, there was a German side interested in him, but offered less than what was requested, but he preferred to stay.
"Inler has been working hard mentally over the past few months. He needed to mature more prior to moving across to a bigger club."
The 26-year-old moved to Udinese in 2007 and has since made 105 appearances for the club, scoring two goals. Inler also captained Switzerland in their 1-0 victory over Spain at last summer's World Cup.
