Preston North End’s 1880 side. Arsenal in 2003-04. And, of course, Boston FC under 15s back in 1986.
The first two names above have both been crowned the Invincibles, for going a campaign without defeat
But that accolade also belongs to a Poachers youth team, back in the days before the blue side of Boston added the Town suffix.
After an all-conquering league campaign, which saw them crowned as champions, the FC youngsters were ready for their moment of crowning glory - the Sunday County Under 15s Cup.
A win would mean the young side had picked up all four trophies on offer that season.
And on that date, Boston did just that with a 2-0 victory over Appleby Frodingham.
The Standard told the opening goal as: “A solid Boston defence dealt with the fast counter raids, from the visiting forwards, and after sustained pressure Boston went ahead, Jamie Ireland bravely put his head to the ball between flailing boots, raced on, and coolly planted the ball wide of the keeper.”
Defenders Mark Cook and Paul Wilde received praise for their performances which led to the side’s clean sheet, especially as, a goal down, Frodingham rallied.
However, the Poachers weren’t there to be defeated after the season they had enjoyed.
And they made it 2-0.
“A goalmouth panic and scramble led to Mark Gittins sealing the cup for FC with a headed goal.
With time running out, FC suffered a blow.
Captain Nigel Vince - who had received a thumbs up for his play, like fellow winger Steve Bryson - had to go off due to a foot injury.
But sub Sttuart Johnson helped FC remain solid.
The season was one of unparallelled success for Boston, having already won the Lincoln Youth League, Presidents Cup and Mellis Trophy earlier that season.
