After leaving a comment on one of Cristiano Ronaldo's Instagram posts, Manchester United defender Lisandro Martinez appears to have divulged the nickname that he uses for the Portuguese football star.

Martinez has quickly become a fan favorite at Old Trafford since arriving at the club in the summer from Ajax. The center-back has played an important role in the recent turnaround in form that the Reds have experienced, so the fans have taken notice.

Diogo Dalot, Martinez, Raphael Varane, and Tyrell Malacia have formed a much-improved defensive backline in recent weeks, which has contributed to United's success in their most recent four consecutive matches in the Premier League.

The Argentine defender seems to have strong relationships with all of his teammates, and he has already established a connection with Ronaldo, who is now 37 years old.

The defender stated, "We are aware of how significant Cristiano Ronaldo's goals are." "It's very important that he scored in order to boost both his confidence and the team's," you might say.
