RB Leipzig secured their third club title after beating hosts Bayern Munich 3-0 courtesy of Dani Olmo's hat-trick in the 2023 Supercup on Saturday.

The Red Bulls caught a fairy-tale start on the road as Olmo broke the deadlock with only three minutes played when he tapped home a low cross from a central position inside the box.

Bayern responded well but neither Serge Gnabry nor Mathys Tel could beat Leipzig goalkeeper Janis Blaswich from promising positions.

The hosts kept it going and were unlucky at the half-hour mark as Leipzig defender Mohamed Simakan almost scored an own goal with a miscued clearance.

Clinical Leipzig doubled their lead and stunned Bayern out of thin air as Timo Werner's through ball allowed Olmo to beat Bayern custodian Sven Ulreich from close range just before the break.

Bayern came out with their guns blazing after the restart, but Leroy Sane's long-range effort went narrowly wide while Blaswhich was again equal to Tel's shot on target at the hour mark.

However, eight minutes later things went from bad to worse for the German record champions as Noussair Mazraoui caused a handball penalty allowing Olmo to seal his hat trick and the win from the spot.

The Bavarians pressed frenetically but Leipzig's defence stood firm to snatch the second Supercup in the club's history.

Harry Kane, who recently joined Bayern from Tottenham Hotspur, made his official debut in the second half to a rousing ovation. 

Elsewhere in Europe, Arsenal kicked off their Premier League campaign with a 2-1 win over Nottingham Forest. Real Madrid began their La Liga season with a 2-0 win away to Athletic Bilbao but lost defender Eder Militao to what looks like a serious knee injury, just two days after Thibaut Courtois was ruled out for the season with a torn cruciate knee ligament.
