Your kidding me right? Barca (up until the last few weeks) have been on fire, and will probably break the scoring record for the spanish league this season. They have scored 4+ goals on numerous occasions. Madrid in contrast won about 10 games in a row one nil whilst playing poorly hence why they kept up with Barca, who went on a bad run as of late. Plus Messi is the best player in the world right now, and can rip any defence aprt. Write Barca of at your peril my friend, if they reproduce their form for the majority of the season, they will be a match any english side.
