Yeovil Town

No English club haunts the giants like this one. Founded in 1895 in Somerset's glove-making town, hence the nickname Glovers, Yeovil Town built the greatest giant-killing reputation in FA Cup history: twenty Football League clubs eliminated while a non-league side, an absolute record, almost always at the old Huish ground with the help of its famous sloping pitch, a sideways tilt that disoriented every visitor. The masterpiece came in 1949, when top-flight Sunderland were toppled 2-1, a feat rewarded with a trip to Maine Road to face Manchester United before 81 thousand people. The club only reached the Football League in 2003, under Gary Johnson, and within ten years climbed to the second tier, the highest point in its history, sealed at Wembley in 2013. The fall back to non-league football followed, but at Huish Park, the modern and mercifully flat home, the identity endures: green and white hoops, rare in England, and the crest's motto as a way of life, Achieve by Unity. Giants beware when the Cup balls come out.
