It would definitely be cool to have an updated version! Wanted to intervene and point out that Robbo is a Scotsman, then I realized it said "British" instead of English. ;-)
Football is a team sport and UCL is a tournament and not a single game. Everyone registered in a team is a winner and not only players who participate in final.
- 2021: James, Chilwell, Mount
- 2023: Stones, Grealish, Walker, Foden
(Hence Paul Lambert, of course.)
I guess there is the option for a second quiz of British (and Irish) players who have played in a losing CL final side.
Ps, it also needs update for the last few finals, although I think only the most recent affects your quiz.
