Trotta has re-joined Sky Bet League One side Brentford on loan until 5th January 2014.
Brentford manager Rösler said: "I remember he joined us on November 24 and he then played every single game for us when we were unbeaten in ten and won seven out of ten. That was due to Marcello coming into the team at the right time and giving us a big lift. He is still very young and he learned a lot last year."
