You have 10 minutes to guess 83 clubs - we're looking for clubs that have made the Europa League or Champions League in their current form: so that's since 2009/10 for the Europa, 1992/93 for the Champions League, and we're after the clubs that have made the group stage.

European football is the golden ticket for so many clubs: just ask the chasing pack in the Premier League who are all shooting for that Champions League star ball this week.
Over the years, we've seen the usual suspects in Europe - the big boys that need no introduction - but we've also been treated to much smaller clubs enjoying their 15 minutes of fame.
That's what makes European football so interesting - the sheer breadth of clubs you could possibly face.
There are literally hundreds of clubs who have made it into Europe, but today we've narrowed it down by two factors: Europe's top five leagues, and the competition in its current form. Can you name everyone to have played in at least the group stage?
