AC Milan ties Barcelona 2-2 in Champions League

AC Milan tied defending champion Barcelona 2-2 Tuesday in a Champions League opener on Thiago Silva's header during injury time.

Barcelona was playing at home and trailed after just 24 seconds when Alexandre Pato dashed through Barcelona's half of the field and slid the ball under goalkeeper Victor Valdes.

Lionel Messi rallied the Spanish champions. The Argentine set up Pedro Rodriguez's 36th-minute goal to make it 1-1 before David Villa curled home a long free kick in the 50th minute. Thiago then tied it 2-2, leaping high to meet Clarence Seedorf's corner kick in the Group H game.
