Bayer Leverkusen opened their Champions League campaign with a resounding 4-0 win at Feyenoord on Thursday, scoring all four of their goals by half-time.

Xabi Alonso's men, who went unbeaten domestically as they won a Bundesliga and DFB-Pokal double and lost the Europa League final last term, blew their hosts away within the first 44 minutes at De Kuip. 

Florian Wirtz needed just five minutes to mark his Champions League debut with a goal, picking out the bottom-right corner after being found by Robert Andrich.

Another of last season's stars, Alejandro Grimaldo, made it 2-0 with a back-post finish following good work from Jeremie Frimpong, then Wirtz volleyed home his second with just 36 minutes on the clock.

Leverkusen had a four-goal lead on the stroke of half-time, Timon Wellenreuther diverting the ball into his own net in a failed attempt to keep out Edmond Tapsoba's header.

Feyenoord were never likely to respond from there, succumbing to the joint-heaviest defeat in their European history, alongside a 4-0 Champions League loss to Manchester City in 2017.

Bayer's resounding victory takes them third in the young Champions League standings, with Milan their next opponents in the competition on October 1.

Data Debrief: Wirtz makes the step up

Wirtz was named Bundesliga Player of the Season as Leverkusen romped to the title last term, and he made the step up to Europe's premier club competition look easy on Thursday.

At the age of 21 years and 139 days, he became the first German player to score twice on his Champions League debut.

Since the beginning of the 2020-21 season, meanwhile, Bruno Fernandes (28) is the only midfielder that has been directly involved in more goals in major European competitions than Wirtz (26 – 14 goals, 12 assists).  

Spain were frustrated on their first outing as European Champions as their Nations League Group A4 campaign began with a goalless draw with Serbia in Belgrade.

Luis de la Fuente's side, who also won the last edition of the Nations League in 2022-23, dominated for long spells and twice saw Lamine Yamal go close in the second half, but were unable to find a way past Al-Ittihad goalkeeper Predrag Rajkovic.

Playing in the top tier of the Nations League for the first time after clinching promotion two years ago, Serbia made a solid start and should have gone ahead after 34 minutes. 

Andrija Zivkovic slipped a delightful ball in behind the Spanish backline for former Real Madrid striker Luka Jovic, but he somehow blasted his effort wide of the left-hand post with only David Raya to beat.

Dani Carvajal volleyed over as Spain upped the ante after the break, but still the Serbian clean sheet remained intact, with Rajkovic called upon to claw Alejandro Grimaldo's dipping free-kick away from the top-right corner.

Yamal curled an effort agonisingly wide just seconds later, and the Barcelona winger would have one final chance to win it with 15 minutes left, jinking into the area and firing goalwards only to see Rajkovic push his effort to safety.

Data Debrief: Serbia stand firm

It was all hands on deck for Serbia at times on Thursday, as every single Spain outfield starter – with the exception of Ayoze Perez – created at least one chance.

Given La Roja racked up 21 shots, however, they will be disappointed with their total expected goals (xG) figure of 1.37, compared to 1.16 from just eight shots for Serbia.

Spain's failure to add penetration to their patient build-up play ensured their nine-match winning run (including one extra-time triumph over Germany at Euro 2024) came to a halt.

Bayer Leverkusen suffered their first defeat in 36 Bundesliga matches, as Leipzig came from behind to stun Xabi Alonso's side 3-2 at BayArena.

Lois Openda struck twice for Marco Rose's, who recovered from 2-0 down to make it two wins from two and move to the summit of the table.

It looked like business as usual for the reigning Bundesliga champions when they scored twice in the last seven minutes of the first half through Jeremie Frimpong and Alejandro Grimaldo.

However, Leipzig replied deep into first-half stoppage time with Kevin Kampl reducing the deficit.

Openda then brought the visitors level in the 57th minute, before a stunning long-range strike completed the turnaround 10 minutes from time, condemning Leverkusen to their first league defeat in 15 months. 

Data Debrief: Leverkusen's long streak comes to a shuddering halt

Leipzig became the first side to beat Leverkusen in a Bundesliga match since Bochum achieved the feat a staggering 462 days earlier.  

The visitors have begun a Bundesliga season with two wins from two for only the second time, also doing so in 2019-20.

They are also now unbeaten in 13 league matches, their longest such streak since Rose took charge.

As for Leverkusen, their invincible streak is officially history, as is their 29-game unbeaten run on home soil.
