Tottenham retained third place in the Premier League with a comfortable victory over a flat Leicester at the King Power Stadium.
With Harry Kane and Christian Eriksen both rested, Spurs initially struggled to break down the hosts until Son Heung-min's superb strike just before the break.
The South Korea forward cut in from the right and hit the top corner with a curling left-footed shot from outside the area.
The impressive Dele Alli then headed in Son's weighted cross after a flowing counter-attack to put the game beyond Leicester.
Spurs had dropped to fifth after wins for Chelsea and Arsenal earlier on Saturday, but have moved back above their London rivals and are five points behind Manchester City in second, with leaders Liverpool a point further in front.
Tottenham now have 36 points after 16 matches, their highest ever tally at this stage in a Premier League season.
Leicester stay ninth despite an end to their six-match unbeaten run in the league.
It is perhaps a mark of Spurs manager Mauricio Pochettino's trust in the likes of Alli, Son and Lucas Moura that he felt able to leave Kane and Eriksen out of the starting side.
Spurs' crucial Champions League group game away at Barcelona on Tuesday explains Pochettino's selection here, but this was still an important game against an in-form Leicester side, with the risk that the visitors could fall behind others near the top of the table.
But unlike the decision not to start Toby Alderweireld in the derby defeat by Arsenal last week, this gamble paid off as Alli, Moura and Son's blend of pace and skill proved too much for Leicester.
Alli and Son provided the only sparks in an otherwise uninspiring first half - the former twice dancing through the Leicester defence only to be denied at the last, and the latter breaking the deadlock with a wonderful strike, the first either side had managed on target.
Collecting a short pass from Serge Aurier on the right-hand edge of the box, Son feinted past Nampalys Mendy to create space before curving a terrific strike beyond Kasper Schmeichel.
Son's start to the season was disrupted by his successful attempt to avoid military service in helping South Korea win the Asian Games, and he subsequently struggled for form. But he has been vital for Spurs recently, with three goals and three assists now in his last six league games.
Alli, meanwhile, has seen his season interrupted by injuries, but he was back to near his best here, drifting between the lines and capping a fine showing with a goal - his 50th in all competitions for Tottenham.
Moura brought the ball forward as Spurs worked a three-on-two, sliding it left to Son, who took his time, fashioned some room and picked out Alli with a terrific cross that the England midfielder met with a diving header past Schmeichel.
Eriksen and Kane did both enter the game in the final 25 minutes - replacing Moura and Son respectively - but by then Tottenham were coasting to victory.
