The 36-year-old failed to score in either leg of the last 16 tie and was castigated by former England manager Fabio Capello after he turned his back on Sergio Oliveira’s free-kick, which ultimately proved to be the decisive goal as the Portuguese side progressed on away goals.
Former Juventus midfielder Alessio Tacchinardi, meanwhile, claimed Ronaldo should be forced to apologise to the clubs fans and his former Italy teammate Antonio Cassano, earlier this month, suggested the former Manchester United star has been a waste of money.
Following Juve’s ignominious exit from the competition Ronaldo was essentially signed to win for the Turin giants, the Portugal international has been linked with a return to Real Madrid with his agent Jorge Mendes said to already be in contact with the Spanish giants.
Writing on Instagram, however, Ronaldo insists his focus is set squarely on hauling in Serie A leaders Inter, starting with this weekend’s fixture against Cagliari, and sent a pointed message to his detractors, reminding them ‘history cannot be deleted’.
He wrote: ‘More important than the number of falls you take in life, is how fast and how strong you get back on your feet.
‘True champions never break! Our focus is already in Cagliari, in the Serie A struggle, in the Italian Cup final and in everything that we can still achieve this season.
‘History can’t be deleted, it’s written every single day with resilience, team spirit, persistence and lots of hard work. And those who don’t understand this, will never achieve glory and success.’
