Minutes after coming on, he almost scored a great headed goal but Ochoa came up with a terrific save.
Ronaldo had earlier teed up Ricardo Quaresma for the opener, with Javier Hernandez's equaliser leading to a tight second half before a hectic finish. Since I began playing on big stages I always imagined playing alongside him.
This baffled Brian Kerr, who was not happy with the amount of time the assistant ref had allowed to be played before informing the referee of the offside, and Didi Hamann too was not impressed as he described the incident as a farce.
But shortly after the match, which ended 4-1 to Los Blancos, Ronaldo unveiled a brand new look consisting of shaved hair which he later admitted was down to a promise he'd made with his club teammates before the Champions League final.
In the 86th minute, Portugal broke through, scoring what they thought would be a victor.
Silva has been compared to a young Fernand Torres, the former Spain striker now playing for Atletico Madrid. He is cool and calm when he has chances in front of goal. I try to listen to him and he tries to help me as best he can. Now we need to think of the next game, which we have to win.
European Champions Portugal and Gold Cup kings Mexico played out an entertaining 2-2 draw in their opening Confederations Cup Group A match in the Russian city of Kazan. "We want to show that we are able to win more tournaments". That has prompted speculation linking him with Paris Saint-Germain and Manchester United among others but Silva, who moved to Milan from Porto earlier this month, insists the four-time Champions League victor remains focused on his country's upcoming matches.
In his next game, Silva scored a hat-trick against the Faroe Islands, when Ronaldo added one goal in another 6-0 victory. "The draw is a fair result without doubt", said Portugal coach Fernando Santos, whose side wore black armbands in honour of the victims of a deadly forest fire back home.
