PSG looked set to go into the break level until VAR intervened, awarding a controversial first-half stoppage-time penalty for handball. Ousmane Dembélé stepped up and slotted the spot-kick home to give the hosts a 3–2 lead at the interval.
The second half remained frenetic, and Kvaratskhelia made it 4–2 in the 56th minute. Shortly after, Dembélé completed his brace, beating Neuer at the near post. Bayern refused to surrender, and in the 65th minute Upamecano pulled one back to make it 3–5. Four minutes later Diaz struck the ninth goal of the night to narrow the gap to 4–5.
The tie remains open ahead of next week’s second leg in Munich, with the winner set to face either Arsenal or Atlético Madrid in the Budapest final at the end of May.
