[ in Sport because it's a genuine question, hoping for answers based on the game, rather than re-hashing the penalties/racism/louts discussions ]
In what proper game (with a decent referee) would Italy have ended the match with 11 players on the pitch ?
The cynical pull-down of Saka was a straight red in most peoples' eyes - he we was through on goal (even if a long way out) and at least one other white shirt was belting up in support on the left.
The studs-up tackle on Grealish was slightly more debatable (it
may have been inadvertent) - but it was a potentially career-ending assault (and possibly fatherhood-opportunity-ending too) - and I've seen loads of those straight-redded too.
Then there was the 'play advantage' nonsense when England had a clear free-kick opportunity denied on the very edge of the box in extra-time - the illusory advantage lasted a microsecond before the ball was hoofed upfield.
There were others too - cynical fouling and faking of injuries were rife by the Italians and blandly ignored by the man in pink.
In the absence of any evidence, I'll just assume that the ref was an incompetent wimp ...
