Tottenham Hotspur delivered a clear message to Pep Guardiola about the challenges ahead after his contract extension with Manchester City, dismantling the reigning champions in a dominant performance.

Guardiola, who signed a new deal on Thursday, endured his worst managerial run as City suffered a fifth consecutive defeat, this time against Ange Postecoglou’s high-flying Spurs.

James Maddison, celebrating his 28th birthday, was the star of the show with two goals in the opening 20 minutes. Erling Haaland missed two early opportunities before Maddison broke the deadlock in the 13th minute, converting a superb Dejan Kulusevski cross. Minutes later, Josko Gvardiol’s misplaced pass was punished, with Son Heung-Min’s clever reverse ball setting up Maddison for his second.

Spurs maintained relentless pressure, and their dominance was sealed in the 52nd minute when Pedro Porro finished off a fine move initiated by Dominic Solanke.

The Etihad Stadium fell silent, with many City fans departing early, missing a stunning moment in stoppage time as Timo Werner’s brilliant play set up Brennan Johnson to net Tottenham’s fourth.

Guardiola faces a significant challenge to steer City back on track and keep their hopes alive for a fifth consecutive Premier League title.
