Arsenal responded with resilience. Midfielder Martín Zubimendi equalized in the 71st minute, setting the stage for a frantic finale. Garnacho struck again for Chelsea in the 83rd minute, seemingly securing a late winner for the hosts at 3-2.

However, in a decisive and immediate response, Arsenal forward Pedro Neto found the back of the net just a minute later, in the 84th, to pull the Gunners level once more at 3-3. Arsenal completed its comeback in the 90th minute, scoring the decisive goal to seal a 4-3 victory.

The match was a physical and contentious affair, reflected in a total of eight yellow cards issued by the officiating crew. The first half concluded with a flurry of bookings, as Arsenal’s Leandro Trossard and Chelsea’s Estevão were both cautioned in the 42nd minute, followed by a yellow for Chelsea defender Cucurella in the 44th.

The second half saw five additional cautions. Chelsea defender Benoît Badiashile was booked in the 65th minute, followed by yellow cards for Chelsea substitute goalkeeper Kepa Arrizabalaga in the 75th and Arsenal’s Mikel Merino in the 78th. Arsenal’s Pedro Neto and substitute Jurrien Timber received yellow cards in the 90th minute and deep into stoppage time, respectively.
