Marco Davide Faraoni is becoming hot property with several Serie A sides said to be watching him closely, but Torino are the first to express a concrete interest.
The 22-year-old joined Watford last summer on a five-year deal from sister club Udinese, who are reportedly considering attempting to sign him back.
Faraoni's agent Giovanni Bia confirmed last week that Udinese are worried that Torino could swoop in for the player but Watford are said to be ready to fight to keep him.
"Faraoni at Watford is a very good young player," he told Sky Sport Italia.
"We could be interested in signing him but it's not an easy operation."
