The Chelsea striker, who is on a season-long loan at the San Siro, found the net for Milan on Tuesday during their 2-2 draw in Serie A.
While there are still plenty of doubts over the Spanish international's ability, Essien is confident that Torres will be a success for the Rossoneri.
"I am convinced we'll see lots of goals from Fernando," he told FIFA's official website. "I really hope he does well for Milan and for himself because he's a top striker and we'll benefit from his goals.
"He's a hard worker both in games and in training and that can also serve him well at Milan. One thing Milan can expect to see is 100% all the time from him."
Milan continue their Serie A campaign on Sunday when they travel to Cesena.
