No one can stop Ronaldo ...

He's got this knack, Cristiano Ronaldo, of making every opponent he faces look mediocre. It doesn't matter who they are, which team they play for or what the game plan is. If Ronaldo gets the ball one-on-one and takes a defender and then a goalkeeper on, Real Madrid is scoring a goal. He's proved it time and again so far this season in this competition, especially over those two legs against Schalke.
A player in the Champions League as relentless and as powerful against top-level opposition has never before existed. Some flicker. Some have a season or two. None measure up to what Ronaldo can do. He has scored 13 goals in this season's Champions League and weighed in with four assists for good measure. He has just matched Ferenc Puskas' Real Madrid goalscoring record, taking 25 matches fewer than the great Hungarian in the process. He is singlehandedly re-writing what it means to be a Real Madrid goalscoring legend. Fans will look back on the likes of Raul and Santillana and wonder if the were ever any good at all.
This is not intended to demean the rest of the Real Madrid squad, but it is intended to set Ronaldo apart as the best individual player in the competition. Real Madrid could be having a bad game, struggling, and all it would take is five seconds of possession for Ronaldo to get a goal.
So no matter who Madrid draws, if the collective can't beat them, the great Ronaldo will.
