Early on in the thread someone mentioned losing biggest games, eg Luton - I remember that, my cuz is Luton fan...
Anyway, biggest game as per the previous 28 pages, is very subjective, dependent on your age, your feelings towards football, success/failure, friends and enemies.
Winning div 1 for the 1st time, must have been massive in its day, ditto FA cup 1st time, and ECWC (as someone previously mentioned, a proper knockout European cup).
So, from my own lifetime, in no particular order, and not neccesarily the 'biggest':
76 tueart overhead kick - watching kids emulate it on the playground, is my 1st city memory.
Tommy Hutchinson OG against Tottenham in FA cup final - 1st really sad time.
Huddersfield 10-1 - unbelievable, can remember getting called in to look at the uni teletext and thinking it must be a typo.
Gillingham - hearing about it 2nd hand from my cuz (same one) who'd been on the phone to his fiancé from stag -do in Vegas, whilst it was on - one of the most expensive phone calls he'd ever made! Retold in detail to me whilst sitting in pool on 2nd floor of Hilton, natch. Earliest I'd ever bought a round of drinks! Most surreal weekend ive ever had.
1-6 - again watching it on teletext, this time in the middle of nowhere in Wales, seeing the score change sporadically to get to 1-3 and then jump to 1-6 :-)
It felt like 35 years of supporting city was the best, and that, yes, finally, it was really going to be different from now on.
Aguerrroooo - scared the wife, with the animalistic roar that came from the depths. 35 years of hurt ... Gone.
There's an excellent montage on YouTube, makes me well up every time.
Back on topic:
If we win the CL, then that would be City's biggest game ever. Imo
But it probably won't be the most emotional, unless we beat Bayern/athletico with 3 goals in the 90+ minutes...
1 game at a time though, 1 game at a time... But I did have a 5-1 premonition for Real...
