Marco Borriello has vowed to take revenge against those who protested against him during Sunday's 1-0 victory at Lecce and win over Juventus' fans.
Supporters held up a banner saying: "Borriello, a mercenary without honour or dignity."
That was an allusion to their belief that the 29-year-old turned down the opportunity to join the Old Lady of Turin a year ago when he left AC Milan for Roma.
But having now joined the Turin giants on loan, with a permanent eight million euro (ê10.2m) deal lined up for the summer, Borriello wants to set the record straight.
"I was disappointed to see this banner at Lecce. In my life I've always conducted myself with dignity, both on and off the pitch, and I have a lot of respect for the Juve fans," he said.
"Milan decided to sell me after signing Ibra (Zlatan Ibrahimovic). Roma showed their interest straight away to buy me outright, while Juve were not in a position to do so.
"I have never boasted about turning down Juve and if today I have been given the opportunity to wear the black and white shirt, it's because I've always behaved in the right way.
"I want revenge and I want to show what I can do. I have five months to convince Juve and their fans."
Revenge is not just against those who have doubted him, though, as Borriello also has a point to prove to those who have discarded him.
Although he has played seven times for Italy and long been regarded one of the top forwards in the country,
Borriello has twice already found himself surplus to requirements at a big club, first Milan and then Roma.
"I have a lot more to give than what I've done so far," he added.
"I've been a bit unlucky in my footballing life: I started playing seriously at Genoa, scoring 19 goals, but then the next season I was out injured for 10 months.
"Then I scored 15 goals in eight months but when I was establishing myself at Milan, Ibra arrived and two days later I decided to go to Roma with a five-year contract.
"Then they changed both coach and owners, and from one moment to the next I was no longer part of their project."
