Manchester United got their 2013-14 UEFA Champions League campaign off to the perfect start with a clinical 4-2 victory over Bayer Leverkusen on Tuesday.
The Red Devils took the lead early through a slightly-controversial Wayne Rooney goal and went into the half-time break with a 1-0 lead—probably a fair score given their dominance. That was quickly followed by a flurry of second-half goals.
Simon Rolfes leveled the scores just after the break with a fantastic shot from outside the box. However, that lead didn't last long, with Robin van Persie taking advantage of some woeful goalkeeping to net from Antonio Valencia's cross.
Rooney scored his 200th United goal when he clipped the ball past the goalkeeper, then laid on an assist for Antonio Valencia to kill off any Leverkusen comeback.
The Germans went on to score a late consolation goal through Omer Toprak after the Red Devils failed to clear a corner, but it made little difference to the final result.
Here are six things we learned from a dominant Manchester United win.
