Football is the most popular sport in the country by a substantial margin. The national football team's best performance was a semi-final at the 1994 FIFA World Cup, when the squad was spearheaded by forward Hristo Stoichkov. Stoichkov is the most successful Bulgarian player of all time; he was awarded the Golden Boot and the Golden Ball and was considered one of the best in the world while playing for FC Barcelona in the 1990s. CSKA and Levski, both based in Sofia, are the most successful clubs domestically and long-standing rivals. Ludogorets is remarkable for having advanced from the local fourth division to the 2014–15 UEFA Champions League group stage in a mere nine years. Placed 39th in 2018, it is Bulgaria's highest-ranked club in UEFA.
