Fred Pentland
A former England international, Pentland spent the First World War interned at the Ruhleben camp near Berlin, where he helped organise football among prisoners. In Spain he became "El Míster", the bowler-hatted Englishman who taught Athletic short passing and fitness, and whose title is still used for coaches across the Spanish-speaking world.
His second spell in Bilbao produced a golden era: two league titles, four consecutive Spanish cups and a 12–1 win over Barcelona in 1931 that remains Barcelona's heaviest defeat.
