The Italian striker returned to Griffin Park for a second spell this week after bagging nine goals in 21 starts last season.
He said: "We signed a lot of good players in the summer I knew my playing time would be restricted.
"The manager wanted me to go out on loan and play. There were other clubs interested but Brentford was the best choice for me.
"Last season I wasn't an automatic choice and I will have to fight for my place in the first 11 again this time.
"That competition keeps everyone on their toes and can only benefit the squad.
"But hopefully I can get some games, score some goals and help the team win promotion."
