Certain goals are considerably more impressive on television than they were to the people who watched them live. The gap is produced by the coverage rather than by faulty memory.
The camera compresses distance
A high, wide camera at the halfway line flattens the pitch, so a curling shot appears to travel a longer and more dramatic arc than it did.
Behind-the-goal angles do the opposite, exaggerating the movement of a ball across the goalmouth in a way no seat in the stand offers.
A spectator in the ground sees the flight from one fixed position, usually from the side and often at an angle where the curve is barely visible.
Replays supply the information the moment lacked
Live, a goal happens once, and much of it is obscured by players, by distance and by the crowd standing up in front of you.
Television shows it again from three angles, slowed down, with the decisive movement isolated and the defenders' positions made clear.
The viewer therefore understands the goal in a way the spectator never will, and understanding is what produces the sense that it was exceptional.
Commentary frames the judgement
A commentator naming what happened, and reacting to it, tells the viewer how remarkable the moment was before they have decided for themselves.
In the stadium there is no such guidance, only noise, and the crowd's reaction is a response to the outcome rather than to the technique.
Goals that are technically subtle benefit most from this, because their quality needs explaining and a stadium supplies no explanation.
The reverse case is just as real
Some goals are far better live: a long-range strike whose speed is genuinely frightening from twenty yards away registers as ordinary on a screen.
The physical sensation of a ball being struck, and the sound of it, do not transmit through broadcast audio at all.
Nor does the collective movement of a stand, which is a substantial part of what makes a late goal feel the way it does.
Why this shapes the historical record
The goals that survive in the shared memory are the ones that filmed well, because footage is what gets replayed and re-ranked.
Goals from eras with fewer cameras are underrepresented not because they were worse but because the record of them is thin.
Any list of the greatest goals is therefore partly a list of the best-covered ones, which is a different thing entirely.
