Paris Saint-Germain commenced their Champions League campaign with a resounding 4-0 victory over Atalanta at the Parc des Princes. The win immediately positions them as strong contenders to retain the title they secured last season.

PSG's dominance was evident from the outset, with Marquinhos scoring in the opening minutes. Khvicha Kvaratskhelia, Nuno Mendes, and Gonçalo Ramos further solidified the victory with additional goals, showcasing PSG's attacking prowess. Although Bradley Barcola missed a penalty before halftime, it was a minor setback in an otherwise commanding performance. Luis Enrique's tactical approach, characterized by high pressing and fluid attacking movements, was clearly on display. However, PSG faced some challenges heading into the match, with key players like Ousmane Dembélé and Désiré Doué sidelined due to injuries. Lucas Beraldo, Kang-In Lee and Khvicha Kvaratskhelia were also not at 100%. The starting lineup for PSG included Chevalier in goal, Hakimi, Marquinhos, Pacho, and Nuno Mendes in defense, João Neves, Vitinha, and Fabián Ruiz in midfield, and Kvaratskhelia, Mayulu, and Barcola in attack.

Atalanta, under the guidance of new head coach Ivan Juric, aimed to maintain their attacking style while improving their defensive stability. However, they were unable to cope with PSG's superior squad and European experience. Atalanta's lineup featured Carnesecchi in goal, Kossonou, Hien, and Djimsiti in defense, Bellanova, De Roon, Musah, and Bernasconi in midfield, and Pasalic, De Ketelaere, and Maldini in attack. Despite being considered the underdogs, Atalanta sought to challenge PSG, but ultimately succumbed to the French side's dominance.

Meanwhile, in Amsterdam, Inter Milan secured a 2-0 away win against Ajax, overcoming recent setbacks in Serie A. Marcus Thuram was the star of the match, scoring both goals with powerful headers. His first goal came just before halftime from a Hakan Calhanoglu corner, and his second followed shortly after the break from another corner. Inter's victory marked a significant turnaround after losing to Inter 5-0 in last season's final. Inter's coach, Cristian Chivu, started Francesco Pio Esposito and Davide Frattesi against Ajax. The Inter lineup included Sommer in goal, Akanji, De Vrij, and Bastoni in defense, Dumfries, Barella, Calhanoglu, Mkhitaryan, and Dimarco in midfield, and Thuram and Esposito in attack.

Ajax, playing at home, struggled to contain Inter's attacking threat and were unable to find the net. Despite their efforts, they proved no match for Inter's strong defense and clinical finishing.

In other Champions League matches on Wednesday, Olympiakos and Pafos played out a 0-0 draw, with Pafos holding on despite being reduced to 10 men after Bruno's dismissal. Slavia Prague and Bodo/Glimt drew 2-2, Bayern Munich defeated Chelsea 3-1, and Liverpool edged Atletico Madrid 3-2.
