Juventus legend Alessio Tacchinardi has demanded an apology from Cristiano Ronaldo for his role in the side's Champions League exit.
The Serie A giants were knocked out of the competition by Porto at the last-16 stage on Tuesday after losing on away goals.
And Ronaldo has been widely criticised for turning his back on the late Sergio Oliveira free-kick which sent Porto through.
Tacchinardi believes Ronaldo shirked his responsibilities after the game by failing to conduct an interview with the press.
And speaking to TMW Radio, he stated his belief that the Juventus fans deserve some answers from the Portuguese star.
"He (Ronaldo) was rested in last weekend's game against Lazio, so what was he doing against Porto?" Tacchinardi said.
"Federico Chiesa went to talk on TV, but I would have expected Ronaldo to do so. He has to make an apology to the supporters."
Despite the condemnation of Ronaldo, Tacchinardi was also scathing about the Juventus team in general, and believes they missed a golden opportunity to progress far in the competition this season.
"For a test this important they should have prepared in a different way," he continued.
"I don't understand why they approached it the way they did after losing the first leg.
"They had the opportunity to attack Porto early on but did no such thing. They totally missed the opportunity."
Ronaldo's future now seems to be up in the air, with some speculation he could leave Juventus at the end of the season.
There are rumours he could make a sensational return to Real Madrid, while big-money moves to China or the United States have also been touted.
Meanwhile Ronaldo and his Juventus side return to action for the first time since the Porto disappointment when they take on Cagliari in Serie A on Sunday.
