Jamie Vardy's 58th-minute strike gave Leicester City victory at Everton and condemned the Merseysiders to their fourth defeat in five Premier League games.
Leicester boss Claude Puel made four changes from the team that lost to Cardiff City on Saturday, including leaving midfielder James Maddison on the bench, while Marco Silva recalled Brazilian Richarlison to his starting line-up.
After a poor first half, the decisive goal came when Everton defender Michael Keane mis-controlled the ball to Ricardo Pereira, who sent Vardy through.
The striker made no mistake with a low drive past Jordan Pickford before celebrating with a cartwheel in front of the travelling Foxes fans.
Gylfi Sigurdsson blasted over from a promising position for Everton but Leicester should have doubled their lead when Harry Maguire somehow missed the target from point-blank range.
Everton, with just one win from their last eight games have now failed to win in their last four home matches while the win moves Leicester up into seventh place, on 31 points, four behind Manchester United.
Ireland captain Seamus Coleman, on the tenth anniversary of his arrival at the club, was dropped to the bench.
Vardy was pleased that Leicester bounced back from Saturday's defeat.
He told Sky Sports: "We needed to put the last performance behind us, which was a disappointing home defeat.
"What better way to do that than to come away from home and start the new year with three points.
"Ricky (Ricardo) has seen me straight away and with one touch he has slotted me through. We'd tried it a few times in the game. This time we got it right and I'm just pleased to see it go in the net.
"You can't have any doubts as a striker, you need to be putting efforts like that in the net.
"It's been a great Christmas period for us but we need to keep pushing on to keep us where we are at the minute and hopefully push on even further."
Everton manager Marco Silva said: "It is a disappointing result and a poor performance, since the first minute.
"We knew before the match what they would come here to do, set up in 4-5-1 blocking space, waiting for our mistake with Vardy on the counter-attack.
"We were in control in the first half and every time we tried to organise the ball we were too nervous. In some moments in the match we were too nervous, and without reason.
"We had one good moment in the match with Jonjoe (Kenny) hitting the crossbar, but there was no reason to be so anxious. If we look to our last results, we are not consistent but it is no reason to be nervous.
"Many moments in the match our fans were behind us. When you play at this level at a club like Everton, we must play to win matches and the players must handle that.
"This afternoon wasn't the best for some of them but it is my job to pass confidence on to them again."
