The striker was introduced at half-time in place of the injured Robbie Keane and Barney certainly made the most of his extended opportunity after clocking up just over 15 minutes on his debut against Manchester United on Easter Monday.
The tenacious front man harried the Bolton back-line and snapped into tackles in an effort to alter the course of a game that the visitors had the better of in the first half. The fans responded to his efforts, giving the 21-year-old an incredible boost as he sought to make an impression at first team level.
"They were brilliant, even when I'm warming up they give me a cheer," said Barney with a big grin. "It helps and makes me feel appreciated and welcome.
"I can describe how much it does help," he added before reflecting on his first big cheer.
"I felt about 6ft 7" out there! They really helped me along the way.
"It was a massive three points for us and we knew it would be tough. We just needed the three points however they came about. We ground it out and the win was the main thing.
"It was a bit of a scrappy game and Bolton are a tough side to play against. It is hard up there but I didn't mind at all because I was playing for the first team. I just tried to work hard, break the play up and get the crowd going.
"I was buzzing that much after the Man Utd game that I couldn't really take it in. I enjoyed it more this time and with it being longer I could kind of relax and try and do more.
"It was just a shame I didn't get a chance on goal again!"
Lee Barnard said the support of the White Hart Lane crowd made it as if a good few inches were added to his frame in the second half against Bolton last Sunday.
