Tell me, have you ever played the game at any point since you were 7 years old? Even five a side? I only ask because if you had, you'd appreciate that this sort of thing happens and when you're the one who scores it, you immediately put your hand up to acknowledge a complete fluke. You're just over analysing it and there's really no need - he simply stuck his foot out in the millisecond he had to think about it.
Indeed. He's admitted it was a fluke, end of.
