Good performances all around with few exceptions.
Messi- a lot to fault him with today, but finishing was impeccable.
Xavi- near flawless performance controlling the midfield.
Alba- always a threat on offense, and his pace tracking back on defense seals the left side from attack.
Other:
Pedro- attack was down the left today, so was isolated. Typical hustle and great ball control in possession.
Montoya- emulates King Eric's calm admirably for his age, well on his way to cementing his spot in future years. Responsible for the goal with a poor clearance, but otherwise solid.
Villa- great runs as always.
Messi- lazy-ass in receiving passes when static between the lines, allowing himself to be poached at least twice by not moving towards the ball to receive.
Song- biggest liability in causing loss of possession/flow, followed by Messi. Holds the ball a bit too long, and sometimes turns into traffic needlessly too far back on the pitch when he has easy outlets.
