The UEFA Champions League returned with a bang on Matchday 1, and no result was louder than PSG's 6-1 demolition of Slovan Bratislava in Paris. Ferran Torres claimed a hat-trick in a one-sided affair that saw the hosts fire an extraordinary 32 shots at goal. Slovan goalkeeper Dominik Takac made eight saves to prevent an even more lopsided scoreline, while Maghnes Akliouche and Achraf Hakimi each delivered four key passes in a relentless attacking display.

Barcelona matched PSG's appetite for goals with a 5-1 thrashing of Feyenoord at Camp Nou. Raphinha scored twice, but the night belonged to 17-year-old Lamine Yamal, who contributed a goal and two assists in a performance that underlined why he is regarded as one of European football's most exciting talents. The Catalan giants sent an early statement of intent in this season's competition.

In Naples, Arsenal secured a hard-fought 1-0 victory over Napoli thanks to a decisive goal from Martin Ødegaard. The Norwegian captain's strike proved enough to earn the Gunners all three points in a disciplined away performance — a result that will satisfy Mikel Arteta as Arsenal look to make a deep run in this year's Champions League. Ødegaard's stats continue to impress, and his influence on Arsenal's biggest nights grows with each passing season.

Liverpool also opened their campaign with a win, edging Atlético Madrid 2-1 at Anfield. Dominik Szoboszlai was the creative heartbeat of the Reds' midfield, threading five key passes as Liverpool found a way past Diego Simeone's typically stubborn defence. It was the kind of gritty, quality performance that Liverpool will need regularly if they are to compete on multiple fronts.

Stuttgart rounded out the evening's action with a convincing 3-1 victory over Viking, powered by Ermedin Demirovic's hat-trick. Deniz Undav provided two assists, and midfielder Angelo Stiller earned an 8.5 match rating for a commanding performance. It was a confident start for the Bundesliga side in their return to Europe's top table.

With five matches delivering 23 goals on a single evening, Matchday 1 set an exhilarating tone for the Champions League campaign. Arsenal, Liverpool, PSG, Barcelona, and Stuttgart all have early momentum, and attention now turns to the next round of fixtures where the landscape will continue to take shape.
