Pep Guardiola's 49th birthday celebrations went flat as Fernandinho's late own goal forced Manchester City to settle for a 2-2 draw against Crystal Palace, while Chelsea's top-four bid was dented by a surprise 1-0 defeat at Newcastle on Saturday.
On a busy day of top-flight action, the pitchside VAR monitor was used in the Premier League for the first time at Norwich, with Tottenham forced to settle for a goalless stalemate at Watford and Arsenal held to a 1-1 draw by Sheffield United.
It was the drama at the Etihad Stadium that took the spotlight as Fernandinho's last-gasp blunder left Guardiola in no mood to party after City's faint hopes of retaining the title suffered another hammer blow.
The champions trail Liverpool by 13 points ahead of the runaway leaders' clash with rivals Manchester United on Sunday.
"It was a tight game. It's difficult to analyse when they shoot from one corner and have no more chances," Guardiola said.
"We had many chances, unfortunately we could not win."
