It's an all-English Champions League final - but will it be Manchester City or Chelsea who will be crowned champions of Europe on Saturday?
Chelsea, European champions in 2012, have beaten Pep Guardiola's side twice in the league and FA Cup in 2020-21.
Up to 16,500 people will be allowed inside Porto's Estadio do Dragao ground to watch.
The final will be decided on the day, with 30 minutes of extra time and then penalties if required.
Each side will be allowed five substitutions, with a sixth permitted for each side if the final goes to extra time.
