Jamie Vardy stepped off the bench to score the all-important goal as Leicester City stunned Arsenal at the Emirates on Sunday night.
The Englishman was named on the bench for the clash, having recovered from an injury he has carried the last few weeks.
He was introduced just on the hour-mark, replacing the brilliant Dennis Praet, and he got the winner in the 80th minute, his 11th in 11 matches against the Gunners.
Thomas Partey made his first Premier League start for the Gunners, and was joined by Granit Xhaka, with the returning Dani Ceballos playing ahead of them.
Saka, Lacazette, and Aubameyang were given the task to lead the line, but Willian missed out with a calf injury.
Leicester on the other hand were largely unchanged, with Vardy the notable absentee from the starting XI.
The Gunners controlled the match for long periods in the opening half, but could not turn their possession into goals as the Foxes sat back and occasionally caught them on the counters.
The first chance of the game however fell to the visitors, after James Maddison saw Bernd Leno off his line and unleashed a long-range shot which sailed inches over the cross-bar.
Two minutes later, Alexandre Lacazette thought he had given the Gunners the opener, but his well-taken goal was controversially disallowed for offside.
The Gunners then came back knocking again in the11th minute, with Hector Bellerin finding space down the right flank after a stunning pass from David Luiz. The Spaniard controlled the ball nicely, but it skidded away from him and the chance went begging.
Mikel Arteta's men kept pushing with Luiz in particular impressive with nice passes all over the pitch, but there was no breakthrough as the half-time went with both sides tied at 0-0.
Leicester looked more assured in the second period and troubled the hosts on a number of occasions.
The best chance however fell to Bellerin in the 69th minute as after Aubameyang chipped a nice ball to the back post, and the Spaniard met it with a crisp volley, which was however saved by Schmeichel.
With 10 minutes to go, the Foxes snatched it with a well-worked goal.
Vardy came close again to doubling Leicester's lead in the 94th minute, but Leno did well to block a goal-bound chip.
Despite enjoying the larger share of possession, the Gunners could not find a way past the Foxes, and they succumbed to their second successive defeat.
