Manchester United jumped out to an early one-goal lead after Danny Welbeck found the back of the net in the 20th minute of the match.
Real Madrid had plenty of opportunities to score a goal in this match but were unable to capitalize. Despite 28 totals shots (14 on net), Real Madrid only scored one goal and that was thanks to Ronaldo.
In the 30th minute of the match, Ronaldo knocked in a header that tied the score with Manchester United and gave the star his 37th goal of the season. Few, if any, were more important than that one, however.
If not for Ronaldo, Real Madrid would have lost this match. Nobody else on CR7's club was able to do what he did, and it makes you wonder just where Real Madrid would be without its star.
Reports have surfaced in recent months that Ronaldo may be unhappy with his current club and could look to continue his career elsewhere. Fellow Champions League participant Paris Saint-Germain could be frontrunners, according to a report by Mike Dawes of the Daily Mail:
Paris Saint-Germain are certain to be among the frontrunners to sign Cristiano Ronaldo if he leaves Real Madrid, according to Arsene Wenger.
It has been rumoured for some time that the Portuguese is unhappy at Real and is unlikely to extend his contract with the club beyond 2015.
And the Arsenal manager believes PSG pack the financial muscle to lure the superstar to France.
Clearly, to speculate where he would go is useless at this time, but there's no question competition will be stiff for the Portuguese star should he decide to leave town.
That's why Real Madrid must do whatever is necessary to keep Ronaldo playing for their side. Money is likely the issue in this instance, but there is no price high enough that should deter Real Madrid from keeping its best player.
Without Ronaldo, this team will be lost. Not only will the club be missing its best goal scorer who can equalize matches when it seems nobody else can, but Real Madrid will also be losing a global icon who has become a marketing marvel.
And to replace such a special player would be nearly impossible for Real Madrid to do.
But all that extra off-the-field stuff is birthed from winning. Real Madrid wins because it has one of the best players on the planet. Ronaldo gives his squad the best chance to win and is worth every penny from both an on-the-field and off-the-field standpoint.
