The match between Chelsea and Ajax quickly heated up with several controversial incidents. In the 15th minute, Ajax midfielder Kenneth Taylor made a dangerous tackle that prompted the referee to consult VAR.

After reviewing the video footage, the initial yellow card was replaced with a direct red card in the 17th minute, leaving Ajax playing with ten men from very early on.

Taking advantage of their numerical superiority, Chelsea quickly pressed their opponents and unleashed a flurry of goals. Just a minute later, Marc Guiu easily tapped the ball into the net from close range after a header from Wesley Fofana, giving the home team a 1-0 lead.

With this goal, Marc Guiu, at the age of 19, became the youngest player in Chelsea's history to score in the UEFA Champions League.

In the 27th minute, Moises Caicedo's long-range shot inadvertently deflected off an Ajax defender, leaving goalkeeper Remko Pasveer completely helpless.
