1987–88 Football League

The 1987–88 season was Port Vale's 76th season of football in the Football League, and second successive (17th overall) season in the Third Division.
 John Rudge's side started the season well, but then suffered following the sale of star striker Andy Jones.
 Just as Rudge seemed to be struggling, the Vale earned a memorable 2–1 victory over top-flight Tottenham Hotspur at Vale Park in the FA Cup Fourth Round.
 They exited the competition at the next stage at the hands of Watford, following a replay.
 Vale's league form also improved, as they finished in eleventh place, helped by midfielders Ray Walker and Robbie Earle, defenders Phil Sproson and Bob Hazell, and goalkeeper Mark Grew.
 Darren Beckford and David Riley were joint-top-scorers with ten goals each.
 Vale exited the League Cup and the League Trophy at the First Round.
The 1993 Football League Trophy Final (known as the Autoglass Trophy for sponsorship reasons) was the 10th final of the domestic football cup competition for teams from Football League Second and Third Division, the Football League Trophy.

The 2000–01 season was Port Vale's 89th season of football in the Football League, and first season back (thirty-eighth overall) in the Second Division.
 A season of two halves, Vale were struggling at the bottom of the table when Isthmian League minnows Canvey Island knocked the Vale out of the FA Cup with a 2–1 victory at Vale Park in 'one of the great shocks in FA Cup history'.
 They also exited the League Cup at the First Round.
 Things turned round in the second half of the season, as a twelve-game unbeaten run in the league was complimented with a League Trophy Final win over Brentford – the second time the club lifted the trophy.
 In the background of this was a financial crisis at the club, which motivated fan protests against Chairman Bill Bell.
