Second best in virtually every area of the pitch, the Rams were taught a footballing lesson by Marcelo Bielsa's United, who on this evidence and that displayed in beating Stoke last week, must be fancied for a solid promotion tilt.
He added: "I'm very much a left-sided player".
The first chance of the match fell his way as Harry Wilson drove into the penalty area and picked out Waghorn, who could only scuff his shot into the path of Mason Mount.
But it was United who went in front barely a minute later. While the defenders stood off him the Polish midfielder calmly picked his spot and curled a shot beyond the reach of Scott Carson for his second goal in two games this season.
"They moved the ball better and we made too many mistakes that led to goals".
And instead it was Derby who were able to level matters in the 12th minute after Liam Cooper fouled Lawrence on the edge of the box.
Leeds United striker Kemar Roofe scored twice for the Whites
But this pulsating game was to take another twist on 22 minutes. It made little difference to a dominant Leeds team with Kemar Roofe scoring twice in addition to goals for Mateusz Klich and Ezgjan Alioski.
Sammy Saiz was proving a tricky character and broke forward to shoot straight at Carson on 28 minutes, before the game settled into a relative lull before the break despite the Rams' best efforts to put pressure on the United defence.
Lawrence got in a cross that hit Craig Bryson and went behind but Leeds nearly scored a third in the 56th minute when Saiz found Roofe.
Former England forward Jay Rodriguez scored twice as relegated West Bromwich Albion got their first win of the season in a sensational 4-3 victory at Norwich City.
"The only positive from today is that it's a good reminder for the players that things won't always go our way like they did eventually last week".
Lawrence dusted himself down to take the free-kick and the winger produced an absolute piledriver that zoomed past Bailey Peacock-Farrell and into the roof of the net.
