The R's manager didn't like the idea or questioning that his team weren't in the Championship contest at Elland Road, with Tyler Roberts and Jack Harrison scoring goals on either side of the half.
The away side would have come into this game full of confidence, in-form, but as underdogs, as they would have backed themselves to cause an upset.
In the end, that didn't happen, as Warburton defended QPR's performance, and insisted that had Hugill taken his chance then it might have been a different ball game altogether.
"You come to Leeds, who are a team established in terms of the squad and their manager's philosophy, for the last x amount of months, to a very tough venue," said Warburton, as quoted by the Yorkshire Evening Post. "We came out second half and showed some really good quality and it's [only] 1-0.
"That ball comes in, it's a great ball in and it's just poor timing from Jordan [Hugill] who has had a great season so far - that goes in, you tell me. They're the fine margins, you put the ball in the net this place [Elland Road] goes quiet.
"You're not going to come here and just dominate. Leeds are a very good team for a reason. We lacked a little bit of self-belief but to say we never got going when it's 1-0 after 70 minutes and we missed a glorious chance, I'm not sure I can agree with that."
This would have been a tricky fixture for Leeds because of the underdog status QPR had under their name before the match, and the quality of players they had at their disposal.
From highly-rated playmaker Eze to powerful hitman Hugill, QPR had the players to hurt Leeds and cause an upset, but Marcelo Bielsa's side held their own, walked away with the points and a clean sheet.
Leeds are now sitting top of the tree after 15 games on 28 points, five points ahead of ninth-placed QPR, as the top ten in the Championship is still very much congested.
