What happened: The UEFA Champions League final between Arsenal and Paris Saint-Germain is heading to a penalty shootout after the two sides could not be separated in Budapest. Kai Havertz had put Arsenal in front inside the opening ten minutes before PSG responded to force the decider. The closing stages also drew furious penalty-claim controversy among supporters reacting online.

Why it matters: A shootout will settle European club football's biggest prize, with Arsenal chasing the first Champions League title in the club's history — the same Arsenal whose run included a statement win over Atletico Madrid. Arsene Wenger, who came within 13 minutes of the trophy in 2006, framed the final as the moment the club has long waited for.

What to watch: The shootout decides the champion; watch whether Arsenal can claim a maiden European Cup or PSG completes the comeback to lift the trophy.
