Worcester Warriors
Rotherham are often considered as Worcester's rivals by those fans who watched Worcester before 2004. However, because Worcester's average attendances have more than doubled since then, a large percentage of the Worcester fan base, many of them newer supporters, see Gloucester as Worcester's main rivals. This is predominantly because of playing them regularly since gaining promotion to The Premiership in 2004, the geographical closeness of the two Cities and various media sources citing the game as a derby.
