Guus Hiddink admitted that John Terry’s equaliser for Chelsea was offside but felt the amount of extra time was correct after Everton’s earlier stoppage-time goal.
Terry’s own goal handed Everton a 1-0 lead at Stamford Bridge in the 50th minute on Saturday, with Kevin Mirallas making it 2-0 six minutes later.
Diego Costa and Cesc Fabregas scored to draw Chelsea level, but Ramiro Funes Mori thought he had won it for Everton with a 90th minute goal.
However, Terry struck with the last kick of the game to keep Hiddink’s unbeaten record back in charge intact – though replays showed he was offside.
“It’s a clear-cut offside that should have been spotted,” Martinez said. “To make it worse, it’s 50 seconds over time. It’s something that’s not good enough.”
However, Hiddink offered a different view, telling BBC Sport: “There was seven minutes extra time, so I said, ‘Ref, okay, they are celebrating at least one minute in the corner.’
“I will not deny it – it was offside because Oscar touched the ball, even though John was technically perfect [with his finish].
“I took some risks [at 2-0 down] and it paid off in a spectacular way. The team is very resilient.”
Hiddink, meanwhile, revealed that Diego Costa had gone to hospital for scans on a shin injury.
“He’s in the hospital now for a scan but we don’t know the result,” said Hiddink. “It’s on his shin. He was in a lot of pain but as soon as we know what is in the report we will put it out there.
“We hope Diego will come out in good health.”
