Matchup to Watch: Real Madrid vs. Manchester United

Undoubtedly, the most prominent matchup of the opening knockout round is Real Madrid taking on Manchester United. The perennial powerhouses both had their sights set on a deep run, but only one of them will reach the final eight.

Madrid continue to be led by dynamic striker and former United star Cristiano Ronaldo, who has already tallied six goals in six Champions League appearances this season. He's joined by a terrific midfield featuring Mesut Ozil and an elite goalkeeper in Iker Casillas.

United are one of the few clubs that can match Madrid's star power. The talented attacking duo of Robin van Persie and Wayne Rooney is going to cause some problems for the Blancos' back line. The Red Devils do have some question marks of their own at the back, though.

Star to Watch: Lionel Messi

Who else? The unstoppable Barcelona forward has shattered the record for most goals in a calendar year and shows no signs of slowing down any time soon. Messi and Co. are set to take on Milan in the Round of 16.

The most amazing thing about the Argentine superstar, and there are plenty of things to choose from, is his remarkable consistency. He rarely goes into a slump, and that is a major advantage for Barca in this type of tournament.

Barcelona were eliminated in the semifinals by the eventual champion Blues last season. But their unbeaten start in La Liga, thanks in large part to Messi's brilliance, suggests they are one of the top contenders to take home the trophy in 2013.
