Cristiano Ronaldo's sister sent a scathing message to Juventus as the Portuguese forward's sensational return to Manchester United was confirmed.

Ronaldo's return to Old Trafford was announced Tuesday, with the Red Devils paying Juventus $17.7 million to bring back its former star.

During his first spell at United between 2003 and 2009, Ronaldo scored 118 goals in 292 games and won three Premier League titles, the FA Cup, and the UEFA Champions League.

Though he enjoyed similar success at Juventus, scoring 101 goals over three seasons and winning five major honors, his career in Turin was marred by controversy.

The 36-year-old reportedly fell out with his teammates earlier this year after skipping training to buy a Ferrari.

In 2019, Ronaldo also had a public spat with then-manager Maurizio Sarri, calling him a "son of a whore" after being substituted during a match.

On Saturday, shortly after his proposed return to United was first revealed, Ronaldo's elder sister, Katia Aveiro, took a swipe at Juventus on Instagram.

"Welcome home my love, welcome to the place you deserve," she wrote alongside a picture of her brother.

Aveiro was slammed for the comment by Italian newspaper Gazzetta dello Sport, which accused her of making a "mockery" of the club.

The outlet claimed Aveiro did not "miss the opportunity" to "shoot an arrow" at Juventus, and called her post "venomous."

Ronaldo has yet to publicly address Juventus since re-joining United, however, he did say on Instagram that he was delighted to be returning to the club at which he made his name.

"I can't even start to explain my feelings right now, as I see my return to Old Trafford announced worldwide," he said.

"It's like a dream come true, after all the times that I went back to play against Man United, and even as an opponent, to have always felt such love and respect from the supporters in the stands.

"This is absolutely 100% the stuff that dreams are made of!"

He added: "I'm right here! I'm back where I belong! Let's make it happen once again!"
