Everton manager Roberto Martinez was left frustrated by the referee's "unacceptable" decision to concede John Terry's late goal in his side 3-3 draw at Chelsea as the Blues captain was in clear offside – and 53 seconds after the allotted seven minutes of added time.

Following a thrilling second half with two goals from each side the Toffees looked ready to take all the three points from their visit to Stamford Bridge after Ramiro Funes Mori scored the 3-2 in the 90th minute. However, Terry, who had previously scored an own goal, equalised the game in the 98th minute when he was a yard offside.

"It was a heartbreaking moment for us because we deserved three points. You can talk about our fantastic performance, our character and the combination of us being hurt but being able to react and score three goals away from home," Martinez admitted.

"Then, there's the understandable feeling of dropping two points from a game in which we had to play seven minutes of injury time, and the last action happens on seven minutes and 53 seconds and John Terry, with the final touch, is two-yards offside."

"Refereeing wise, you cannot justify (the extra-time added on). It cost us two points and you can imagine the players are feeling really down, but they have no reason to feel that way because it's two points taken away from us and our performance was good enough to win the football game.

"The fourth official and referee are talking all the time. When the ball went out of play, before the action [of Chelsea's third goal], the fourth official said time was up. But then the offside decision was as clear as you are going to see as well - it's a major error."

Martinez, meanwhile, played down the concerns over Bryan Oviedo after the Costa Rican was force to be replaced by Ramiro Funes Mori in the second half of the game after suffering a new injury. The Spanish boss suggested the substitution was just a precaution as the right-back "should be ok" soon.

"Bryan's injury is not serious and he should be ok. We will assess him over the next 24 hours," he said. "It was more a knock rather than anything else. We expect that Bryan will be ok."
