Xavi is the best passer in the world. And Manchester United didn't seem to care one bit.
Here are Xavi's personal stats for the day:
3 attempts on goal (one on target, two off)
124 passes made out of 136 (91 percent accuracy)
11.95 Km run.
Those stats are impressive, but there's a not so obvious one that trumps them all and sets a fine example on how (and why) United were overrun.
Look at Pedro's goal (the first one of the night). Andrés Iniesta plays it to Xavi. Xavi receives and has the ball for one...two...three...four...five...SIX seconds without anybody coming in to close to him down (never mind tackling him), picking Pedro out absolutely alone for an easy score in the first half.
You just can't let the world's best playmaker do that.
Letting Xavi think and giving him space and time to work was the defining stat in this game.
Sometimes seconds are the most valuable stat in football.
