The 20-year-old has been hampered by injuries since arriving on-loan from Serie A club Udinese in the summer and had to wait until Saturday's 2-2 draw with Blackpool to make his full debut for the Hornets.
"I like it very much here in England," he told the official website. "My family and my girlfriend are now in the country, I have a house and everything is falling into place so I'm happy.
"It is very important to have my family here; it is only three hours away from Italy so it is good and comfortable for me. The players told me it is a physical game; tough players and tough games.
"But I can play that kind of game also, here at Watford the coach we have wants to try to play a passing game which is why I came here. We are trying to play a different kind of game that a lot of the other clubs in the Championship don't play.
"The important thing is when the coach thinks I'm ready to play, I'm ready. I have watched games this season and that has been a help."
