Two goals up at half-time following a first half of relatively few chances for either side, the team rallied in the second period and did not permit any possible showboating or running up of a score by a full-strength United side. In fact, it was the visitors who would have been more anxious to hear referee Mr Styles' final whistle after Gus Poyet reduced the deficit.
"Obviously everyone is disappointed after losing to, perhaps, the potential champions," reflected David back at Spurs Lodge on Monday.
"No it didn't become routine. We came strong, but we were always vulnerable on the counter attack as the game became spread in the second half and we survived one or two breaks. We were quite solid, believe it or not, in the first half and Keller didn't have to make a save in the second.
"It is no use keep talking about it as you can over analyse games. The fact is, when we got our act together, we played strongly and I always say that I look at ability, attitude and application. The attitude and application was fully there - particularly when we had to try and come back from 2-0 down.
"I am not down, I am disappointed, very disappointed with the scoreline - but I am not down."
Next up is the busy festive period, with a trip to the South Coast to play Portsmouth followed by Charlton and FA Cup third round day against Crystal Palace at the Lane.
"I am very excited about the rest of the season. Our next challenges are Portsmouth and Charlton and we have to go in there and be very determined."
With the January transfer window looming, David concluded by saying he is hopeful of some activity.
"We are looking to strengthen if we can, of course we are."
David Pleat agrees that it was vital that Manchester United's trip to the Lane did not result in a routine away victory for the champions as he offered his considered verdict on the weekend action.
