Promoted Sampdoria stuns AC Milan at San Siro

Newly-promoted Sampdoria marked its return to Serie A with a stunning 1-0 win over AC Milan on Sunday at the San Siro.

Andrea Costa scored the lone goal in the 58th minute, helping Sampdoria defeat 2011-12 runner-up Milan on the opening weekend of the new season.

Minus offseason departures Zlatan Ibrahimovic and Thiago Silva, AC Milan found the woodwork twice, but failed to slip a shot past Sampdoria goalkeeper Sergio Romero.

Costa fired Sampdoria in front before the hour mark as he turned a header past Milan goalie Christian Abbiati.

Milan tried to respond through Mario Yepes, but Romero pushed his shot off the post, Kevin-Prince Boateng hit the frame later in the half and Mathieu Flamini had a late chance cleared off the line.

Sampdoria finished sixth in Serie B last season, but won its playoff to secure promotion. Sampdoria could not have asked for a better start in Serie A, while Milan will be left to pick up the pieces after a forgetful opener.

Milan lost just twice at home last season, going 12-2-5.

Inter Milan 3, Pescara 0

Pescara, Italy - Wesley Sneijder and Diego Milito scored two minutes apart in the first half and Inter Milan cruised to a 3-0 victory over newly-promoted Pescara on Sunday at the Stadio Adriatico in Serie A.

Sneijder opened the scoring in the 16th minute and Milito followed in the 19th as Inter opened the new season with a convincing road win. Unlike Milan rivals AC Milan, which dropped its opener to promoted Sampdoria at home.
