Manchester City suffered a shocking 4-0 defeat to Tottenham at the Etihad on Saturday, marking their fifth consecutive loss and ending their 52-match unbeaten home streak.
James Maddison netted twice in a dominant first half, with Pedro Porro adding a third against his former club and Brennan Johnson sealing the win.
City’s first defeat on home soil from open play since the eve of the 2022 World Cup leaves them still five points adrift of Premier League leaders Liverpool, who play their game in hand at bottom-of-the-table Southampton on Sunday.
A great day for Tottenham eases the pressure on Ange Postecoglou as they climb into the top six.
City boss Pep Guardiola has committed himself to turning around the poorest run of his managerial career after extending his contract till 2027 this week.
But hopes his new deal could revitalise a City side, that have won an unprecedented four consecutive Premier League titles, proved short-lived.
Rodri paraded his Ballon d’Or trophy to the home fans before kick-off as his name was lit up across the Etihad pitch by firelight in an ostentatious show of support for the Spanish midfielder.
The 28-year-old is not expected to play again this season after suffering knee ligament damage in September and his absence has been at the heart of City’s demise.
Guardiola’s men did start strongly as Guglielmo Vicario denied Erling Haaland and the Norwegian had another shot deflected wide.
But the momentum of the match completely swung on Tottenham’s first serious attack after 13 minutes.
Dejan Kulusevski’s teasing cross picked out Maddison who applied a cool first-time finish.
Maddison had found himself frozen out of Postecoglou’s starting line-up in recent weeks and was keen to prove a point to his manager.
Son Heung-min’s inventive pass freed the England international inside the box and he dinked the ball over the advancing Ederson to double Spurs’ lead.
Inconsistency has been the scourge of Tottenham’s season so far.
A 2-1 home defeat to Ipswich before the international break saw Postecoglou’s men slip to 10th in the table.
But they have now twice won comprehensively in Manchester after a 3-0 win over United at Old Trafford.
Dominic Solanke was denied by a fine Ederson save with the chance to make it 3-0 before half-time.
Spurs, though, were not to be denied seven minutes into the second period.
The excellent Kulusevski crossed for Solanke and he patiently laid the ball back for Porro to blast home from close range.
Haaland clipped the bar from an almost impossible angle as City laboured to find a response.
Instead, they were hit with one final sucker punch as Timo Werner eased past Kyle Walker and crossed for Johnson to tap home at the far post.
The one glimmer of hope for City may be the return of Kevin De Bruyne after a two-month injury absence as a late substitute.
City will play Liverpool next at Anfield in the Premier League. The blues have not won there since 2003.
