Three points against City would be critical for that plight.
Pep Guardiola's side, 16 points ahead of second-placed United, now need three more points to finally secure this season's league title.
And the Tottenham manager drew attention to the difference in the £450million that City have spent since Pep Guardiola became manager, emphasising that whilst he aspires to catch them next season, they can not compete financially. "The Premier League is so, so tough", Guardiola said. "We need to do our thing and hopefully we can finish it off next week".
"It's one of the best by far". The runaway leaders have seen their Champions League hopes torn to shreds by Liverpool and were denied, if only temporarily, their title celebrations by derby rivals Manchester United last Saturday evening.
After sweeping through most of the season in regal fashion, City had crashed down to earth with a bump over the last 10 days.
Spurs' fourteen-match unbeaten Premier League run is ended by a City side on course for their third title in six years.
Despite completely dominating the first-half, there were some nervy moments as Tottenham got back into the match until Raheem Sterling scored City's decisive third.
Sergio Aguero was pushed through the pain barrier in midweek against Liverpool, but that was with a Champions League semi-final place on the line. It's much more important what these players have done. "They have unbelievable players; it was an aggressive performance from them". Three successive defeats, something they have not experienced since February 2016 during Manuel Pellegrini's reign, have thrown a spanner in the works of the City machine. "We did it.we nearly did it!"
Leroy Sane nearly gave City the lead in stunning fashion after four minutes, crashing a back-post volley against the post following Sterling's delivery from the right.
Sane nearly scored City's third goal on 29 minutes only to be denied by Davinson Sanchez who raced back to block the German's effort.
They eventually broke the deadlock on 21 minutes as Jesus latched on to a long ball from Vincent Kompany before slotting past Hugo Lloris.
City's celebrations were barely over by the time they were 2-0 up just three minutes later.
While it was a clear foul, the contact appeared to be made just outside the area, yet, to Tottenham's fury, Jonathan Moss awarded a penalty that Gundogan slotted home easily. It was so easy for them.
Running onto Harry Kane's defence-splitting pass, Eriksen's shot hit City's Aymeric Laporte and deflected back onto the Tottenham midfielder on its way past Ederson. He struck from close range after Gabriel Jesus' shot was parried.
