The UEFA Champions League roared back into action with two massive nights of football, putting Club World Cup champions Chelsea and European powerhouse Liverpool to the test. Both English giants faced formidable opponents in challenging encounters that delivered drama, goals, and significant talking points for the start of their European campaigns.

At Anfield, Liverpool continued their perfect start to the season with a thrilling 3-2 victory over a stern Atletico Madrid side. Manager Arne Slot, celebrating his 47th birthday, saw his team establish a remarkable early lead, going two goals ahead within just 332 seconds. Left-back Andy Robertson broke the deadlock in the fourth minute with a thumping finish, followed swiftly by Mohamed Salah, who doubled the Reds' advantage two minutes later. This rapid succession of goals marked a new club record for Liverpool, never before having been two goals ahead so quickly in any European tie.

However, Atletico Madrid, under Diego Simeone, mounted a stunning comeback through midfielder Marcos Llorente, who produced a double to level the score. The intensity of the match was palpable, with a controversial VAR decision denying Liverpool a potential penalty after a challenge on Jeremie Frimpong. Despite these setbacks and a resurfacing lack of defensive focus that Slot had observed last season, Liverpool's new captain, Virgil van Dijk, showed a killer touch. He clinched victory with a thumping header in the 92nd minute, sending Anfield into raptures and securing Liverpool's perfect start. The match also saw a significant debut for British record signing Alexander Isak, who was named in the starting lineup despite recent fitness concerns, and a notable statistical anomaly as Liverpool fielded a starting XI without an English player in a club competition for the first time ever, with Conor Gallagher representing England in an Atletico Madrid shirt. Simeone, for his part, received a red card after tangling with the crowd near the dugout.

Meanwhile, Chelsea faced a tough trip to Bayern Munich, where they were handed a stark lesson on the Champions League stage, ultimately falling 3-1. Despite their recent Club World Cup triumph, Chelsea struggled to match the German champions, who now boast former Blues loanee Nicolas Jackson. Bayern's victory was spearheaded by a double from former Tottenham striker Harry Kane, who continued his prolific form. The opening goal came controversially through an own goal by Chelsea's Trevoh Chalobah, who deflected a low cross from the excellent Michael Olise into his own net. Olise, a former Chelsea academy player, showcased why Bayern pursued him so actively.
