The popular striker has been with the club for over four years and has witnessed many a cracking atmosphere at the Lane, but he feels this time it was just that little bit extra special and Robbie believes the fans really defined the meaning of home advantage.
"I was speaking to Pat Jennings and even he said it was the best atmosphere he's experienced in a long, long time," said Robbie back at Spurs Lodge this week. "I have to agree with him, the crowd were brilliant and the fans probably don't realise how important they can be to the team when they are like that.
"I know it's an old cliche, but they are like a 12th man and made a big difference on Sunday. The game was one of the big highlights of my time here, probably the biggest.
"Against teams of such quality you know it is going to be tough, but I thought we matched them in everything and the effort from the lads was second to none.
"We have to continue like that, it is okay doing it against Chelsea, you need to apply it the same in other games - the next one being Reading.
"Hopefully we will take a lot of confidence from the game," added Robbie who, not surprisingly, reported that there has been a spring in the step of the players at Spurs Lodge.
"Of course, with beating the champions in the manner we did and deserving to win the game. To go behind and come back to win showed a lot of character."
Robbie Keane described the victory over Chelsea on Sunday as probably his most memorable occasion in a Spurs shirt.
