Karim Adeyemi starred as Borussia Dortmund romped to Celtic, while Barcelona and Manchester City picked up their first wins in the restructured Champions League on Tuesday.

Adeyemi scored a first-half hat-trick as Dortmund beat Celtic 7-1 at home. It was the second major win for a German team in the competition after Bayern Munich beat Dinamo Zagreb 9-2 on matchday one.

Robert Lewandowski gave Barcelona the lead as the Spanish giants cruised to a 5-0 home win over Swiss side Young Boys, while his former teammate İlkay Gündoğan guided City to a 4-0 win at Slovan Bratislava. Erling Haaland scored his 42nd goal in his 41st Champions League game.

City lost 0-0 to Inter Milan in their opening game while Barca responded to a 2-1 defeat in Monaco, the team’s first defeat under new coach Hansi Flick.

Mikel Arteta’s Arsenal outclassed his former team Paris Saint-Germain with a 2-0 win, with Kai Havertz and Bukayo Saka scoring for the Gunners in the first half. PSG coach Luis Enrique’s attempt to leave Ousmane Dembélé out didn’t work.

Arteta enjoyed a successful 18-month loan spell at PSG while still a teenager at Barcelona.

Dortmund fans cry foul

Although the Dortmund team appears to have adapted very well to the new competition format – last season’s losing finalists have ten goals from two games after a 3-0 win against Club Brugge – their fans expressed their opposition to the reforms clearly and clearly tifo criticizes UEFA.

This season UEFA changed the structure of Europe’s premier competition, adding four more teams. The group stage was abolished in favor of a league system in which each of the now 36 participating teams competes once against eight opponents in a first phase of the competition.

UEFA claimed the changes would make for more balanced games, but Tuesday’s results – big wins from Barca, City and Dortmund – appear to refute that claim.

There were more big wins on Tuesday as Inter Milan beat Red Star Belgrade 4-0 and beat tournament debutants Brest Salzburg 4-0 away to secure their second win in as many games in Europe’s premier competition.

Iranian striker Mehdi Taremi fired a penalty past Israel and Red Star goalkeeper Omri Glazer and set up two more goals for Inter, just hours after his country fired a barrage of rockets at Israel.

Senegalese striker Abdallah Sima scored twice for Brest, taking his tally to three goals in two games after scoring in the French side’s opening 2-1 win over Austrian champions Sturm Graz.

Also on Tuesday, Bayer Leverkusen defeated AC Milan 1-0 in Germany thanks to a clever move from Victor Boniface.

Daniel Bragança scored late to earn Sporting Lisbon a 1-1 draw at PSV Eindhoven.

Kaan Kairinen’s brilliant free kick was enough for Prague to draw 1-1 in Stuttgart.

Behind one of the goals, the Stuttgart fans performed a huge choreography with the slogan “Back in Europe”. It was the German team’s first Champions League home game since the 1-1 draw against Barcelona in February 2010.
