The striker scored nine goals in 29 appearances on loan at Brentford last season and missed a penalty on the final day of the campaign which would have earned the Bees promotion to the Championship.
He recently rejoined Uwe Rosler's side on loan until January to gain further first-team experience after making just three substitute appearances in his Fulham career.
The 20-year-old, who spent time at Napoli and Manchester City before joining Fulham in 2009, is determined to eventually make his mark at Craven Cottage.
"In 2008, I had the opportunity to undertake this adventure in England with Manchester City and I'm happy with my choice," Trotta told tuttomercatoweb.com.
"Clubs here follow you with great attention, especially if you are very young. Then I had the good fortune to work with Martin Jol, who is a great coach.
"This is an important season for me because I hope to help Brentford to achieve promotion and to have a chance in Fulham's first team, with whom I have a contract until 2015.
"My model? I was lucky enough to train with Dimitar Berbatov and I tried to learn as much as possible from him. He is one of the strongest players in the Premier League's history."
