The Whites face a test this Saturday away at Derby and Lampard can not help but admit to having been impressed with what he saw at Elland Road, with bags of energy on display from the hosts.
Lampard saw Leeds pull his team apart with pace and movement as his first home game in charge ended in a chastening defeat.
And just two minutes later United were in front thanks to a brilliant finish from Klich who received the ball on the edge of the area from Pablo Hernandez and then produced a gem of a shot into the bottom right corner for his second goal in two games.
Derby brought in Martyn Waghorn and the £5million signing from Ipswich had a chance in the fourth minute but scuffed his shot and Mason Mount could not convert the rebound.
It was a superb strike but Derby were level in the 12th minute when Lawrence sent a free-kick from just outside the box over the wall and through the hands of Bailey Peacock-Farrell who should have done better. Tom Lawrence's direct running was too much for Luke Ayling, the Leeds right-back bringing down the Welsh global outside on the edge of the penalty area.
Jay Fulton scored the only goal as Swansea beat Preston North End to make it two wins from their opening two matches.
Leeds regained the lead through Kemar Roofe, the striker rising between two defenders to loop a header into the net from Ezgjan Alioski's left-wing cross after the home side had failed to clear their lines.
"Leeds have come to our place and looked more confident than us.it comes down to the basics of football, if you don't move the ball quickly enough and you're not fearless enough and your quality is not quite good enough then it's hard to get out and we weren't good enough today".
The reprieve was only temporary and two goals in four minutes swung the game decisively in the visitors' favour.
Leeds struck again with devastating speed.
