Marco Rose's Bournemouth became the first English team to win the club's first three European games since Sunderland’s Cup Winners’ Cup campaign in 1973/74. The Cherries recorded a famous win over the former European giants AC Milan, who weren't helped by their goalkeeper Mike Maignan’s sending off in the first-half.
Former Bundesliga wingers Justin Kluivert and Amine Adli scored with an early penalty-kick and a late free-kick, respectively, to help the Premier League side to a 3-0 victory. Rose's men will face out-of-form Manchester United on Sunday with the hopes of extending their winning run to four games in all competitions.
Ruben Amorim’s side also lost their first game away from home to Benfica, who lead the standings ahead of Bayer Leverkusen on goal difference. Ferencvaros and Olympiacos also won their first three games in the league phase of the Europa League.
Meanwhile, former Borussia Dortmund fullback Sergio Gomez scored a brace as Real Sociedad bear Lillestrom 6-0 away from home. Anderlecht also recorded the first win of their European campaign with Marten Winkler, who joined the Belgian giants from Hertha BSC in the summer, on the scoresheet against Jagiellonia.
Fellow Germany midfielder Mika Bauer scored for Celtic against Celta Vigo, but his club suffered a fourth successive defeat in Europe. Former Bundesliga stars Jean-Philippe Mateta and Jesper Lindstrom scored for Crystal Palace and RB Salzburg in the 2-2 draws for their teams at Beşiktaş and Celje, respectively.
In the Europa Conference League, eight teams maintained their perfect start, including Paris Brunner's Monaco at the expense of SC Freiburg. Marc-André ter Stegen and Julian Brandt helped Ajax to a hard-fought 2-0 win over Atalanta, while Fabian Hürzeler's Brighton were held to a goalless draw at Jablonec.
