Leyton Orient have got off to their best league start since the club was formed in 1881, and currently sit on top of League One, with five victories from five matches. But there was a time - over 40 years ago - that Orient truly stuffed Chelsea, and almost got one over on Arsenal too.
I know, because I was there.
It was a cold and wet Saturday in February in 1972, when the mighty Chelsea (FA Cup winners just two seasons before) went to Brisbane Road for a 5th Round tie against lowly Orient - who were then near the bottom of Division Two - which many at the time saw as an easy passport into the Quarter-finals.
Chelsea's team that day included David Webb, Ron Harris and Peters Osgood and Bonetti, and when Osgood scored taking Chelsea 2-0 up, we thought it was all over. Several kids, like me at the time, started to cry.
Then, in one of the greatest comebacks in FA Cup history, Orient scored three times to run out winners (see video below).
And Orient's reward for beating Chelsea was a quarter-final tie at home to Arsenal, who were then the FA Cup holders.
Well, we all rocked up at Brisbane Road again, dreaming of a place in the semis, but Arsenal manager Bertie Mee ensured that Orient were taken seriously, and the Gunners ran out 1-0 winners. It was an even game, however, and Orient took the game to Arsenal and were unlucky not to have forced a draw.
A draw with Arsenal was something Orient managed in the same competition in 2011, however, but Arsenal ran out 5-0 winners in the return leg at the Emirates.
Arsenal also beat Orient in the semi-final of the FA Cup in 1978, after Orient had beaten Chelsea at Stamford Bridge in the quarter-final replay.
Happy days, and great memories. I still tear up when I watch that 1972 3-2 win on Youtube.
