Our ever-enthusiastic midfielder struck in injury time to grab a deserved share of the spoils in the 1-1 draw - and went completely mad.
He immediately listed it in his top three of all-time 'stadium reactions' in a game he's played in.
Not surprisingly, Gus doesn't find it too difficult to hark back to that November night a year on at Spurs Lodge.
"It will be difficult to forget that goal," he reflected.
"It was the kind of feeling you cannot pay for, no amount of money, not even if you are a multi-millionaire.
"It is only if you are lucky enough to play football, to be on the pitch in this type of game and to have the luck to be there at the right moment to score that goal.
"To tell everyone how I felt after that goal - and I've told a few people this already - I was driving home two hours later and I was still celebrating.
"There were so many things still going on inside. It was too much.
"Even though it was only for a point, it was the way it happened and that we deserved perhaps even more.
"I don't lie, it was probably one of the top three reactions I have ever seen in a stadium.
"It was magnificent, unforgettable, and for me, something that will always be there."
Gus Poyet says he'll never forget last season's dramatic equaliser against Arsenal at the Lane.
