Tottenham powered to the top of the Premier League with an impressive 2-0 win against Manchester City on Saturday.
Jose Mourinho's side are two points clear of Chelsea thanks to goals from Son Heung-min and Giovani Lo Celso at the Tottenham Hotspur Stadium.
Tottenham took the lead after five minutes as South Korean forward Son ran onto Tanguy Ndombele's lofted pass, beat the City offside trap, and slotted a cool finish under Ederson.
It was Son's ninth league goal this season and his 11th in all competitions.
City dominated possession after Son's goal and thought they had equalised in the 27th minute when Aymeric Laporte fired home.
But Gabriel Jesus controlled Rodri's cross with his arm before setting up Laporte and the goal was disallowed after referee Mike Dean consulted the pitchside monitor.
Lo Celso came off the bench to score with his first touch just 35 seconds after his introduction.
The Argentine midfielder netted his first Premier League goal in the 65th minute, driving his shot past Ederson after Harry Kane's sublime pass prised open the City defence.
Spurs transformed into title contenders
On the one-year anniversary of Mourinho's appointment, Tottenham are unbeaten in their last eight league games since losing to Everton on the opening weekend of the season.
Mourinho's team are on a four-match winning run in the league and have been transformed into genuine title contenders just months after finishing outside the top four last term.
Tottenham, who last won the top-flight title in 1961 and haven't lifted a major trophy since 2008, would surrender pole position if Leicester beat champions Liverpool at Anfield on Sunday.
City are languishing in 10th place, eight points behind the leaders after their first defeat in 10 games in all competitions.
Pep Guardiola's timid side look a shadow of the swaggering outfit that won successive league titles in 2018 and 2019.
Next weekend, Tottenham face a fascinating clash with London rivals Chelsea, who maintained their fine form as Federico Fernandez's first-half own goal and Tammy Abraham's strike sealed a 2-0 win at St James' Park.
