Inter triumphant in Zanetti's 800th game

The 39-year-old Argentine began his Inter career 17 years ago, playing in a 1-0 Serie A win over Vicenza on August 27, 1995, after joining from Banfield, an unfashionable Buenos Aires club.

Since then he has won five Serie A titles, four Italian Cups, one Champions League, one UEFA Cup and one Club World championship.

Zanetti's fellow Argentines Esteban Cambiasso and Rodrigo Palacio scored Inter's goals in the play-off round first leg.

Thirty matches were played on Thursday involving teams ranging from five-times European champions Liverpool to Neftchi Baku from Azerbaijan.

Neftchi achieved a 1-1 draw at home to APOEL Nicosia, who reached the quarter-finals of the Champions League last season.

Russian club Anzhi Makhachkala, who have splurged millions on players like Cameroon forward Samuel Eto'o and Dutch coach Guus Hiddink, beat AZ Alkmaar 1-0 with a second-half goal from Ivorian forward Lacina Traore.

The match was played in Moscow after UEFA prevented Anzhi from playing at their base in the violence-plagued Dagestan region for security reaons.

Norway's Tromso, based inside the Artic circle, produced a shock 3-2 win over Serbia's Partizan Belgrade.

Athletic Bilbao, beaten finalists last season, trounced HJK Helsinki 6-0 and a 78th-minute own goal by Andy Webster gave Liverpool a 1-0 win at Hearts.

Aritz Aduriz and Markel Susaeta scored twice each for Athletic with Inigo Perez and Andoni Iraola sharing the others.
