Felipe Melo is determined to overcome a difficult start to his Juventus career and help the club win trophies.
The Brazilian midfielder made a big-money move to Juve from Fiorentina last summer after also being linked with Arsenal.
However, he has struggled to produce his best form and in December was awarded the 'Golden Bin', given by fans to the worst signing of the season.
Melo has improved since Alberto Zaccheroni replaced Ciro Ferrara as manager and changed the formation.
But he still is not satisfied and has told supporters that he will show his true quality before long.
"I have played for many different clubs in Brazil and I have always won," he told Tuttosport.
"I am also part of the Brazil side, a national team that has always won everything.
"I am used to winning and if I came here it means that I want to win with this jersey, too."
