Quiz I wanted to see for a while... but are you sure you included all teams? Atletico Madrid is certainly missing. I am pretty sure that teams like Fenerbahce, or Lokomotiv Moscow did play in the CL since 2010. You could also accept just "Viktoria" for Viktoria Plzen.
Thanks for pointing those teams out. I know that Atlético definitely played in the Champions League, as did Lokomotiv Moscow (they played in it in 2019-20). I probably thought that I had already included them (Atlético first appeared in 2013-14, at which point I had assumed that they'd been in it at least once before). Fenerbahçe, surprisingly enough, didn't play in the Champions League this decade, with the Süper Lig being dominated by Galatasaray and Beşiktaş. Going through ten years' worth of competitions is predictably exhausting, so I thank you for pointing out things that slipped my mind. Funnily enough, I'm planning to put out a sequel on teams that have played in the Europa League in the 2010s, which is an even larger task, considering that a total of 56 teams play in it every year.
You are right, Fenerbahce did play in qualifiers only, never made it to a group stage this past dacade. Great quiz. Also laborious, that is for sure! Can't wait for a Europa League edition.
Thanks! I have a giant colorcoded spreadsheet with over 200 teams that played in the Europa League this decade, so it's going to be quite the endeavor.
Thanks, I wanted the years to have some type of color instead of the regular blue and white every time so I thought I'd put the winners. I published this quiz in the middle of the 2019-2020 season, so I had to wait for about a month for a champion to actually be crowned.
