What really happened at the time has been revealed in an extract from the former England defender's biography.
Published in The Sunday Times, the book reveals: "As Campbell walked off the pitch he heard someone shout abuse and make the gesture of a hand fashioned into the shape of a gun.
"It was pointed in his direction. As the index finger pulled the trigger, the fan's lips made a little explosion and the mouth stretched itself into a bayonet smile.
"The fan did not flinch. He continued to stare. And to sneer.
"At half-time Campbell was not his usual self in the Arsenal dressing room. 'I can't go on'', Campbell said gently.
"Gary Lewin, the Arsenal physio, said: 'What?'
"Thierry Henry recalls: 'He had his boots off and I said, ''Come on Sol, put those on and let's get on with the game''.'
