Derby County's six-game unbeaten run was emphatically ended by a 3-0 home defeat by Aston Villa.
The Rams had their chances in the first half but were surpassed in the second half.
It was scoreless until the 74th minute, but three quick goals from John McGinn, Tammy Abraham and Conor Hourihane gave the visitors a deserved victory.
This was Derby's first defeat at Pride Park Stadium since Leeds United's 4-1 win in August.
After the last international change of the year, they now have to wait two weeks before their next game in Sheffield Wednesday.
Rams boss Frank Lampard made two changes to the team, which started their 3-1 win over Birmingham City last weekend.
Fikayo Tomori was recalled in central defense at the expense of skipper Curtis Davies, who fell on the bench. So Richard Keogh took over the captain's armband again.
Elsewhere, there was a start for Mason Bennett, who was used because of the injured Martyn Waghorn (thigh).
Waghorn's absence meant that 18-year-old midfielder Max Bird was among the substitutes.
Mason Mount (ankle) and Craig Bryson (calf) and George Evans (hip), Joe Ledley (hip / back) and longtime adventurer Marcus Olsson (knee) were again in arrears.
Andre Wisdom, Alex Pearce, Jacob Butterfield, Ikechi Anya and George Thorne had no place in the squad.
After the 2-0 win against Bolton Wanderers named Villa boss Dean Smith an unchanged team.
Birkir Bjarnason returned to the squad after a groin injury, but had to settle for a place on the bench.
This was the annual Remembrance meeting of the Rams. On this occasion, a commemorative coin of the Royal British Legion was used for the coin toss and met a minute's silence before kick-off.
Villa went in the sixth minute just before the lead.
Scott Carson's weak kick went straight to Albert Adomah. His cross from the right freed Jonathan Kodjia in the back post – but he went to him when he had to hit the target.
At the other end, Bennett ran down the right side before bridging a dangerous cross that Harry Wilson and Duane Holmes were avoiding in the middle.
Bennett then did well to exorcise James Chester, and the ball went to Tom Lawrence, who shot narrowly past 25 meters.
After Lawrence was pulled out of Keogh, Lawrence squeezed from the left to the inside, but shot directly to keeper Orjan Nyland from the edge of the grounds.
Borrowed Villa front man Abraham had a good fight with Chelsea club mate Tomori – and was well volley after a loose ball in the box.
Wilson then made an important clearance after Kodjia had returned another Adomah flank in the danger zone.
In the 27th minute Wilson tried to catch Nyland from all 35 yards and his shot was certainly well hit – but the keeper got behind it and made the defense.
It was Carson's turn after six minutes.
After Adomah had exchanged the wings, he hit a cross from the left and Abraham's header was scored by the Derby keeper around the post.
In the 38th minute the Rams almost opened the lead.
Craig Forsyth's long ball was well hunted by Jack Marriott, but was rejected by Nyland's legs. Wilson's follow-up was then blocked by Chester.
The danger remained, however, and seconds later saw Wilson, as his left foot from the keeper acrobatically tilted over the crossbar.
Shortly thereafter Jack Grealish broke out for the visitors and shot wide from 20 meters.
Tom Huddlestone turned into Lawrence's corner, while Kodjia also came out of Adomah's center at the other end.
Just before the break Derby had another great chance to break the bag.
Carson's kick caused all sorts of problems in the Villa defense, and the bouncing ball was kicked off by Lawrence in the box. He controlled, but could not suppress his effort and raised a shot of eight meters over the pole.
Villa changed one change at half-time and brought in Ahmed Elmohamady for Neil Taylor, who seemed to be struggling with injury.
Derby was injured with an injury strike five minutes after the start of the second half when Bennett stopped with apparent muscle tension. He was replaced by Florian Jozefzoon.
Villa had the ball in the net in the 53rd minute. McGinn's deflected shot was hit by Carson by Abraham, but the flag was offside against the striker.
The visitors gained momentum, and Abraham threatened to break free just to make Tomori an important lifeline.
In the 59th minute Elmohamady's cross from the right saw Abraham in the middle was not marked, but he came from eight meters to him.
Moments later, on the hour, Kodia's left center was shot over by McGinn.
Derby was at stake and Grealish played in Kodjia after 64 minutes – but the former Bristol City man scored a first goal well.
Abraham then could not connect to Elmohamaday's cross, and the Rams were somehow still on a par.
Just 20 minutes from time, Lampard brought Scott Malone for Holmes and switched to three at the back to turn the tables.
Yannick Bolasie replaced Kodjia for Villa – and opened the first goal in the 74th minute.
Bolasie defeated Jayden Bogle on the left and his pinpoint cross was passed by Carson past McGinn six meters away.
Wilson shot wide-field with a rare shot from the Rams in the second half.
In the 78th minute, however, they fell further back. McGinn became a provider when his articulated cross was driven home from the left, a short distance from Abraham.
Forsyth was injured while trying to stop Abraham and was replaced by David Nugent.
Marriott drew a 20-yard meter behind the post as Derby tried to find a way back into the game.
In the 84th minute Villa went ahead, however.
Huddlestone fouled McGinn just outside the box, and Hourihane's free kick was too good for Carson.
Derby was well and truly beaten and the final whistle could not come soon enough.
