Juventus forward Cristiano trained with his teammates on Tuesday ahead of their opening Champions League Group D clash with Atletico Madrid in Spain.
And the former Real Madrid player will be preparing himself for another hot reception at the Metropolitano stadium.
Juve met Atletico in the last last season with Ronaldo scoring a hat-trick in the second leg to overturn a 2-0 deficit from the first match.
Ronaldo was jeered throughout by the home support in the first leg, prompting the attacker to hold up five fingers to fans during the match, representing the number of Champions League trophies he has won.
The 34-year-old is hoping for a less hostile return this time round. "In Madrid, I played many times and they were always a tough opponent," he said after the Champions League draw last month. "I hope they don't crush me again at the stadium, calling me unsportsmanlike."
It is unlikely that Atletico fans will pay much attention to his hopes on Wednesday night.
