Ferhandinho’s last-minute own goal cost Manchester City victory over Crystal Palace as the Premier League champions fell further behind leaders Liverpool.
Saturday’s showdown, though, was defined by two penalties being denied by VAR – one for each team.
Palace were the first to miss out, when John Stones brought Wilfried Zaha in the 16th minute at Eastlands.
The Eagles, who won this fixture last season, did take the lead through new signing Cenk Tosun in the 39th minute.
The Turkish forward, on loan from Everton, headed home at the back post after Gary Cahill had nodded a corner across the area.
Then in the 71st minute, City boss Pep Guardiola thought his side had a penalty when the referee ruled Jairo Riedewald had handled a Joao Cancelo cross, but the VAR review overturned the decision after it showed the ball had struck his leg before bouncing against his arm.

The Eagles were eight minutes away from a victory, before Sergio Aguero entered the fray.
Aguero got City on level terms in the 82nd minute when after sliding in at the back post to convert a Gabriel Jesus ball for his 250th goal for the club in all competitions.
Five minutes later the Argentine made it 2-1 with a fine, angled header from a Benjamin Mendy cross from the left.
The drama wasn’t over as Palace grabbed a point after Zaha powered past Stones, with his cross deflecting in off Fernandinho.
And Guardiola says: “It was a tight game and unfortunately we could not win it.

“I told them… try to control Zaha on the counter-attack. It’s difficult to analyse when they shoot one corner, have no more chances, and we did many times and unfortunately could not win. We take it one game at a time.”
