[3] They also reached the third round of the FA Cup for the first time; they held First Division leaders Middlesbrough to a goalless draw at Loakes Park, and only lost the replay to a last-minute goal.
[4] Courtesy of the Isthmian League win, they were invited to enter the Anglo-Italian Semi-Professional Trophy, a match played on a home-and-away basis against Monza, winners of the Coppa Italia Semiprofessionisti.
They finished 20th, and were relegated on goal difference, but thanks to their eighth Isthmian League title, made an immediate return to the higher level, which had been renamed the Football Conference.
Under the management of Martin O'Neill, Wycombe won the FA Trophy for the first time in 1991, beating Kidderminster Harriers at Wembley in front of a then record attendance for the competition of 34,842.
In 2013–14, they avoided a return to the Conference only on goal difference, but bounced back to reach the play-off final the following year, only to lose to Southend United in a penalty shoot-out.
[9] In 2017–18, they were promoted back to League One and two years later they reached the second tier of English football for the first time in their history after beating Oxford United 2–1 in the play-off final.
[10] Although they lost their first seven matches of the 2020–21 EFL Championship, and were 12 points adrift in mid-February, they recovered to finish 22nd and their relegation was only confirmed on the final day of the season.
