However, the Italian accepts it is a long shot.
He said, “Watford is the club of my life. They gave me the platform and opportunity to play week-in, week-out. As a result of their trust in me I managed to demonstrate my value there.
“The Watford supporters always acclaimed and lionized me and will always be in my heart.
“I don't think that there are many players around who can say that they had their own fan chant like I had at Watford. Fans serenaded me at each and every game.
“I am sorry that I could not stay on because I was really very happy at Watford.
“The club, the Pozzo family and the fans will therefore always have a special place in my heart.
“If one day Watford knock on my door I would of course go back. For me it's a dream. But at the same time I don't believe in fairy tales. It's tough, if not impossible and I am realistic about it."
