#2 Oldham Athletic
Oldham had gained promotion to the top-flight just before it became the EPL, in 1991, ending a period of 68 years outside the division. They therefore are down in history as one of the founding 20 clubs of the inaugural EPL season, certainly one of the least-known.
In 1992-1993, they stayed up on goal difference, after a tense finish to the season which saw them battle to key wins over Liverpool and Southampton, thus relegating rivals Crystal Palace.
The following season Oldham reached the FA Cup semi-final and were going through until Manchester United equalised in the last few minutes of extra-time. They comfortably lost the replay and their season never recovered: they won none of their remaining seven fixtures, finishing second last in the league.
Oldham have spent 14 seasons in League One now, and look to have found their level of football.
