Bayern Munich secured a crucial 2-1 Champions League win over defending champions Paris Saint-Germain at Parc des Princes on Tuesday, despite being reduced to ten men before halftime.

Former Liverpool winger Luis Diaz was both hero and villain, scoring twice in the first half before being sent off for a reckless tackle on Achraf Hakimi.

Diaz shines, then self-destructs

Bayern made a blistering start, taking the lead inside four minutes when Diaz pounced on a rebound after Michael Olise’s shot was parried by Lucas Chevalier.

The German side dominated play and nearly doubled their advantage through Aleksandar Pavlovic and Serge Gnabry, who struck both posts in one attempt.

Diaz eventually got his second, dispossessing Marquinhos and calmly slotting home. Bayern appeared in full control until disaster struck moments before halftime, Diaz launched into a dangerous two-footed challenge on Hakimi, earning a straight red after VAR review.

PSG rally but fall short

With Bayern down to ten, PSG pressed relentlessly after the break. Luis Enrique introduced Goncalo Ramos and Joao Neves to tilt the balance, and Neves eventually pulled one back with a superb volley from Kang-in Lee’s cross.

Despite sustained pressure and several late chances, including another Neves header that went narrowly wide, PSG couldn’t break down Bayern’s disciplined defense.
