Cristiano Ronaldo scored twice as Real Madrid came from behind to stun Paris Saint-Germain 3-1 in the first leg of their heavyweight Champions League last-16 tie on Wednesday. Ronaldo scored his 100th Champions League goal for title-holders Real from the penalty spot late in the first half to cancel out Adrien Rabiot's opener for the French side at the Santiago Bernabeu, set up by Neymar. The Portuguese star then turned the ball home from close range with seven minutes left before Marcelo secured what could turn out to be a decisive first-leg lead ahead of the return in Paris on March 6 and sent nearly 80,000 home fans into raptures.
