London. On a night filled with squad rotations, costly mistakes, and a brilliant solo goal from 18-year-old Estevão, defensive lapses proved fatal for both Manchester City and Barcelona as they suffered significant Champions League defeats on Tuesday.

In Pep Guardiola’s 100th Champions League match as City manager, his heavily rotated squad—featuring 10 changes from Saturday’s Premier League loss to Newcastle, with Erling Haaland starting on the bench, struggled to contain Bayer Leverkusen’s rapid transitions in a 2-0 defeat. Alejandro Grimaldo opened the scoring with a low drive into the far corner in the 23rd minute, before Patrik Schick headed in a second in the 54th.

“It feels wonderful and we gave everything until the last second,” Schick told broadcaster DAZN.

Estevão Shines as Barcelona Sinks
Chelsea cruised to a 3-0 victory over 10-man Barcelona at Stamford Bridge, sealing their third league-phase win and tightening the race at the top. Barcelona suffered its second defeat of the stage and went down to 10 men just before halftime when Ronald Araújo received a second yellow for a forceful challenge on Marc Cucurella.

An own goal by Jules Koundé in the 27th minute put Chelsea ahead after confusion in Barcelona’s goalmouth. Estevão doubled the lead in the 55th with a superb solo effort as he held off two defenders, and Liam Delap added a close-range finish in the 73rd. Barcelona has now lost four of its last 10 games in all competitions, increasing pressure on coach Hansi Flick.

City missed the chance to climb to the top of the standings, leaving the top three unchanged ahead of matches Wednesday for Bayern Munich, Arsenal, and Inter Milan. Borussia Dortmund moved up to fourth, and Chelsea rose to fifth, both joining City on 10 points. Barcelona fell to 15th, while Juventus climbed to 21st as its revival continues.

Mourinho’s Benfica Earns First Win
Guardiola’s former rival José Mourinho finally secured his first Champions League victory with Benfica, beating Ajax 2-0 in Amsterdam thanks to Samuel Dahl’s sixth-minute volley and a late strike from Leandro Barreiro. Ajax remains winless, losing all five Champions League matches and winning just one of its last 10 games.

Aubameyang Lifts Marseille; Dortmund Routs Villarreal
Pierre-Emerick Aubameyang struck twice in four minutes early in the second half to guide Marseille to a 2-1 comeback win over Newcastle. Serhou Guirassy scored a brace as Dortmund routed 10-man Villarreal 4-0 to end a three-match winless run.

Juventus edged Bodo/Glimt 3-2 in the Arctic Circle, needing a stoppage-time winner from Jonathan David after the hosts equalized in the 87th. Substitute Kenan Yildiz was involved in all three Juventus goals.

In Istanbul, Canadian forward Promise David scored the lone goal in Union Saint-Gilloise’s 1-0 win over injury-hit Galatasaray, which played without top scorer Victor Osimhen and finished with 10 men after 18-year-old Arda Ünyay was sent off.

McTominay Strikes Again
Scott McTominay scored the opener as Napoli beat Qarabag 2-0, though the match paused briefly when Qarabag’s Kevin Medina appeared to be knocked unconscious by a McTominay shot. Napoli fans marked the fifth anniversary of Diego Maradona’s death during the match.

Athletic Bilbao settled for a 0-0 draw against Slavia Prague, leaving both clubs outside the qualifying positions after five games.
