Inter Milan ended Arsenal’s unbeaten run in the Champions League with a narrow 1-0 victory at San Siro, thanks to a disputed first-half penalty.
The match reached a pivotal moment just before halftime when Mikel Merino was called for a handball in the box, though he had minimal time to react to Mehdi Taremi’s flick.

Despite Arsenal’s protests, the Video Assistant Referee (VAR) upheld the penalty decision, and Hakan Calhanoglu stepped up to calmly convert it, slotting the ball down the center to put Inter ahead.
Arsenal responded with an intense second-half push, creating numerous scoring opportunities.

Gabriel came close to an equalizer with a powerful header from a corner, only to be denied by Denzel Dumfries, who cleared the ball off the line.
Inter’s goalkeeper Yann Sommer also played a crucial role, producing a superb one-handed save to keep out a curling effort from Kai Havertz.
As Arsenal pressed forward, Havertz had another close attempt blocked by Yann Bisseck, further frustrating Mikel Arteta’s side.
Despite their efforts, Arsenal couldn’t find a breakthrough, and Inter held firm to secure the win.

This defeat marked Arsenal’s first loss in four Champions League games this season, leaving them 12th in the tournament’s 36-team league phase, while Inter celebrated a crucial victory in front of their home crowd.
