Everton manager Roberto Martinez called the level of refereeing "diabolical" after John Terry's controversial injury-time equaliser cost the Toffees two points at Stamford Bridge.
Terry scored in the 98th minute despite being in an offside position as Everton let another late 3-2 result slip. The Toffees had taken a two-goal lead when the Chelsea captain put the ball into his own net and Kevin Mirallas put the visitors in control.
But quick goals from Diego Costa and Cesc Fabregas turned the game on its head before Ramiro Funes Mori looked to have won the game in the 90th minute. And Martinez was left angry with the decision to award Terry's equaliser which was scored after the allotted seven minutes of injury-time was up.
He told Sky Sports: "I'm not frustrated. I'm very angry. Top and bottom, we lost this football game because of a horrific decision right at the end. It's clearly offside and it was over the time of seven minutes. If you look at the time of when we conceded, it's well over the time. That's something which is clear cut.
"We scored two very good goals, conceded two and the game became very frantic. We showed incredible character and resilience to get the third goal - it was what we deserved. We have had that taken away in a very unfair manner.

"It's a long ball, a couple of headers and all you want is the referee to do his job. The linesman is in a good position and John Terry is clearly, clearly, offside.
"Unfortunately, you don't get anything. No one will get anything out of it. We won't get the two points back and that's the most frustrating part of it. You're looking at a game which was a fantastic game of football - for every fan and neutral - but the level of refereeing is diabolical in that respect. That's really, really hurtful.
"Nobody deserves that. It's something that is down to the decision. If you ask any Chelsea fan or anyone connected with Chelsea, they will tell you it was offside and over the time.
"That's not a point of view, it's clear cut. It should have been given and it's an incredible decision to see given in the best league in the world."
