On a wild Champions League night with stellar teenage scorers, Kylian Mbappé also struck four including the second-fastest Champions League hat trick ever to show the old guys have still got it. Real Madrid star Kylian Mbappé scored the second-fastest hat trick in Champions League history by netting three times in just under seven minutes at Olympiakos on Wednesday.

Mbappé scored in the 22nd, 24th and 29th minutes - after Chiquinho had put Olympiakos ahead in the eighth. The France international also scored a fourth goal in the 60th after Mehdi Taremi had scored for the hosts in the 52nd.

That was Mohamed Salah's in six minutes, 12 seconds for Liverpool against Rangers in October 2022. Mbappé is now second fastest, with his second hat trick in the competition this season, and fifth of his Champions League career.

Arsenal topples Bayern

Arsenal took Bayern Munich's top spot in the standings with a 3-1 win, title holder Paris Saint-Germain romped to a 5-3 win over Tottenham with Vitinha scoring a hat trick, and Liverpool slumped to another loss at Anfield, 4-1 against PSV Eindhoven.

At age 17 - the same as when Mbappé was launching his Champions League career at Monaco - Lennart Karl and Viktor Dadason both scored Wednesday, and so did 18-year-old Geovany Quenda.

Karl's exquisite first-timer for Bayern leveled the game in the first half but barely bothered Arsenal in a clash of the runaway Premier League and Bundesliga leaders.

Only Arsenal now has five straight wins in the Champions League after Inter Milan lost 2-1 at Atletico Madrid, whose captain José María Giménez won it with a stoppage-time header.

In Copenhagen, Dadason set the Danish champion on its way to a three-goal lead in a 3-2 win over Kairat Almaty.

In Lisbon, Quenda opened the scoring in Sporting's 3-0 win over Club Brugge. The exciting wing-back will join Chelsea after the season.

At the other end of the age scale, 38-year-old David Luiz scored with a soaring header to help Pafos to a 2-2 draw with Monaco. He became the second-oldest scorer in the Champions League, behind only another veteran defender Pepe, who was approaching his 41st birthday when he scored for Porto two seasons ago.

Atalanta won 3-0 at Eintracht Frankfurt with three goals in five minutes starting with Ademola Lookman in the 60th.

Dadason's big future

Viktor Dadason already was the third-youngest scorer in the Champions League 's 34-season history last month in Copenhagen's 4-2 loss at Borussia Dortmund. Only Ansu Fati and Lamine Yamal were younger than the Iceland youth international when they scored their first goals for Barcelona.

The 6-foot-3 (1.93 meter) Dadason set Copenhagen on the way to a three-goal lead Wednesday with a header in the 26th. The Danish champion had to hang on for a 3-2 win over Kairat Almaty, which scored twice late on yet ended the night 35th in the standings above only hapless Ajax.
