Looking forward to this game, Barca want to go for the kill.. While Real need to win or at least not lose.
Barca missing both first choice defenders in Pique & Puyol, so they'll be essentially lining up with two midfield players in Mascherano & Song at the back.
Most likely be of a similar pattern to the game played in the cup earlier in the season, Real playing counter-attacking football with Barca having majority of the ball.
