By the end of Euro 2016, we'll have surely been won over by some players about whom we know very little.
But for many of us, the first time we encounter many of the players from countries like Iceland, Austria and Albania will be in the form of Panini stickers.
If you get more than 10 out of 20 on this tough quiz, you'll have done very well - a lot of these folks are very obscure, and may remain very obscure by the time the tournament is over.
Good luck!
