AC Milan made their mark in the Europa League with a 4-0 win at Red Bull Salzburg thanks to a hat-trick from Alphadjo Cisse.
The teenager was the star of the show in Austria, doing so at 19 years and 358 days, becoming the youngest Italian to win the treble in European competition.
Goncalo Ramos was also on target for the Rossoneri, who sent off Filippo Terracciano late on as they bounced back from defeat to Benfica in their league opener.
Their Serie A rivals Juventus beat Celta Vigo 2-1 to make it two wins.
Nick Woltemade equalized for Juve after Hugo Alvarez had given the home side the lead, the striker on loan from Newcastle United pouncing on a poor defense to score his second goal for the club.
Juve completed the turnaround in stoppage time, Randal Kolo Muani heading home from Andrea Cambiaso’s superb cross.
There were mixed fortunes for Premier League teams. Sunderland needed a stoppage-time winner to beat Portuguese second-tier Torreense 2-1, while Bournemouth were more comfortable in beating Sturm Graz 3-0. Crystal Palace failed to complete a clean sweep for the English sides as they lost 3-2 at Lyon.
Scottish champions Celtic lost 4-1 at Benfica and there was an equally strong account in Poland as Lech Poznan were beaten 4-0 at home by Bayer Leverkusen.
Hoffenheim’s poor start to the season continued as they beat Besiktas 3-2 at home to keep the Bundesliga side still without a point in the competition. “Marseille” is also pointless after a 1-0 defeat at home to “Olympiakos”.
Their Ligue 1 rivals Rennes beat OFI Crete 2-1, Abdelhamid Ait Boudlal scoring in the 90th minute. There was also late drama in Croatia as Dion Beljo’s 96th-minute penalty gave Dinamo Zagreb a 1-0 win over Anderlecht.
Elsewhere, Real Sociedad earned their first point with a 1-1 draw with Union Saint-Gilloise.
