Trotta - who is on loan with the Bees from Fulham - is determined to succeed where Macheda failed and make it big in the Premier League.
He said: "I don't think we can compare our situations, let alone our goals.
"Federico scored a decider in the race for the title and above all he was playing for his club, while I am on loan at Brentford.
"I think we will only be able to draw parallels when I'll be able to score a goal for Fulham in the Premier League.
"For now I need minutes under my belt, I need to play.
"That's how you hit form and find continuity. That's the only way you can improve and that's the only way I can play in the Premier League one day."
