A model who once injured former Spurs ace Kevin-Prince Boateng during a raunchy sex session has taken aim at Cristiano Ronaldo.

Stunning Melissa Satta joked about the Portuguese star's relevance in Serie A following his recent move to Juventus during an interview.

Ronaldo, who has yet to score in Italian football, will play Boateng's current club Sassuolo on Sunday.

But Melissa wasted no time in chiding him with a "who is he?" barb ahead of the footballers' league meeting.

The 31-year-old German-born Ghanaian midfielder joined the northern Italian club in July this year from Eintracht Frankfurt. He has previously played for Tottenham and AC Milan.

A few years ago, wife Satta caused a stir when she revealed that a thigh injury that sidelined Boateng for one month was caused by the couple's 10 times-a-week sex romps.

Ahead of the Juventus versus Sassuolo league fixture, Satta has raised tensions by 'dissing' star forward Ronaldo.

She joked: "Who is Cristiano? I only have eyes for Boateng."

However, the hot model confessed that her husband always says that "CR7 is the best player in the world".

Meanwhile, Boateng recently announced that Hollywood could be a future career path for him when he eventually retires from football.

The 31-year-old said in an interview that he sees himself "along the same lines as Denzel Washington", an actor Boateng thinks is "really good".
