After some wonderful football in recent weeks this was a victory we had to grind out.
Middlesbrough took an early lead through Alen Boksic after nine minutes and were then happy to play with nine men behind the ball.
But having posed the question 'can you break us down' the answer was 'yes' as two goals in three minutes just before and after the hour mark from Teddy Sheringham and Les Ferdinand won the day.
"This is a significant sign to me," admitted Glenn. "I think this result is better than the Newcastle result last week.
"I've seen here in the past that was maybe the game we would have come out with a draw or even lost. To win is a big sign for us. There is a lot of belief in that dressing room and now we have to maintain it."
Glenn said that his management team and the lads had 'read the script' in preparing for Saturday's encounter.
He explained: "We felt they would give us a lot of possession and they dropped the second striker in very deep, got a lot of people behind the ball and when we conceded so early into the game I felt it was going to be very frustrating. It panned out that way in the first half.
"I felt we could still win the game at half-time and I asked the players if they felt the same and the belief coming out of the dressing room was good.
"We said we had to get our game going, be a little bit sharper. We were just off sync. We weren't playing poorly but it was a matter of not quite finishing off some of the moves we put together.
"We adjusted it a bit, asked Gus to play a little wider and we stretched them that little bit more. When we did that we opened them up.
"We turned it around. We had to turn it around and that shows the character of this side as well as some of the nice football we've played."
And the boss cited the crowd's patience as another key to a win that took us up to seventh in the Premiership at close of play.
He added: "We probably had enough possession to have won three games but when we found ourselves 1-0 down we had to be patient and not get too frustrated.
"They got a lot of players behind the ball, we thought they'd do that, but we showed that patience and so did the crowd. They didn't turn on the players and that is a great sign."
Glenn Hoddle claimed Saturday's win against stubborn Middlesbrough was a 'significant sign' to how his Tottenham team is progressing.
