Barcelona's Champions League hopes were dealt a serious blow Wednesday night at the San Siro, courtesy of an impressive defensive performance from AC Milan.
The Rossoneri defended steadfastly throughout the night, keeping their collective shape in the face of Barcelona's probing attacks, and benefiting from the diligent work of several key players. When given the opportunity, they attacked with ferocity and finished clinically.
Barcelona, meanwhile, didn't offer much to answer Milan's disciplined defensive display. Adding to the difficulty of zipping passes along a rough pitch, Lionel Messi was unable to find any joy on the dribble. As a result, the Blaugrana lacked their usual inspiration in attack, and hardly tested Christian Abbiati in the whole of the 90 minutes.
It was a perfect storm of unfortunate circumstances for Barcelona, and one they'll be hoping to avoid entirely in the return leg. Let's have a closer look at exactly what led to their shock defeat.
