Substitute Cedric Soares looked like being the European champions' hero with his 86th-minute deflected shot, but Moreno's header from a corner spoiled the Southampton defender's celebration of his first worldwide goal to snatch a 2-2 draw for Mexico. So we have to stay calm and think about the next game.
Portugal celebrated, but the game was then held up as the referee waited for the assistant to check the replay, before the goal was ruled out roughly 40 seconds later because Pepe had been adjudged to be offside. "We faced the European champions, a team that plays at a very high level, and we played equal to them". "Mexico was better, more aggressive".
"Hector Moreno's goal handed Mexican football a huge result", he said.
The FIFA Player of the Year, who had scored 11 goals in seven games coming into Sunday's encounter, was perhaps not as influential as usual but was still named man-of-the-match.
"The team had nearly won and we suffered in the last minute, but this is football".
Ronaldo is at the centre of a transfer saga after the player told Real Madrid he wants to quit the club.
His 30-metre strike bounced off the bar and Nani hammered the ball home but the referees disallowed the effort for an offside infringement earlier in the move. And they (Portugal) are the current European champions.
"In the end it was a well-deserved result after how we played today", Mexico coach Juan Carlos Osorio said.
He attracted headlines last week after being accused by a Spanish prosecutor of defrauding the country's tax authorities.
Ronaldo made a great run from near midfield to set up Quaresma's 34th-minute goal.
Ronaldo obliged after Carlos Salcedo made an error to allow him in on goal before finding Quaresma in acres of space who collected the ball calmly before waltzing past Guillermo Ochoa to score the opener.
Soares scored late with a right-foot shot from inside the area after Mexico midfielder Hector Herrera gave the ball away, and Moreno's equalizer came with a firm header from close range after a corner kick one minute into injury time.
