If it were easy to shut down Barca more teams would do it. I though RM played them well and on another day might have come away with a more favourable result. Can't blame Ronaldo, but both of his misses were crucial. Barca haven't built their reputation on a house of cards. They withstood the pressure, built some up of their own and were able to take the chances when they came. You can't bank on Ronaldo missing either chance like that or Kaka's chance bouncing off of Valdez on that side of the post. Look how Barca's second came... it was lucky. I thought the better team won it, but there wasn't as much in it as we've seen in the past.
The result has set things up for an interesting 2012 plus they are both playing well in UCL also.
