Football is the most popular sport in Iceland. Iceland hosted the U-18 European Championship in 1997, but an Icelandic national team has qualified for the final competition of a major tournament only five times—thrice by the women's national team at UEFA Women's Euro in 2009, 2013 and 2017, and twice by the men's team at UEFA Euro 2016 and the 2018 FIFA World Cup. The only Iceland teams to advance past the group stage at a major tournament are the women in 2013 and the men in 2016. Iceland's most famous football player is Eiður Guðjohnsen. He has won two Premier League titles for Chelsea F.C. as well as La Liga, Copa del Rey and the UEFA Champions League title for FC Barcelona.
