Athletic Club is a Spanish football club from Bilbao in Biscay, Basque Country, Spain. The club has played in the Primera División of La Liga since its start in 1928. Of the founding members, only Real Madrid, and FC Barcelona have never been relegated. Athletic are historically one of the most successful clubs in Spain. They have won La Liga on eight occasions.
Athletic confirmed on Wednesday that for the next three seasons, the logo of Bilbao-based oil company Petronor will adorn the famous red and white striped shirts.
The 110-year-old club, who retain a policy of only recruiting Basque players, have until now shunned the chance to cash in on shirt advertising, although they did promote the local region on their jerseys for free during their UEFA Cup campaign four years ago.
