Chelsea had taken the lead in the first half through Michael Essien but Nicky Butt scrambled an equaliser in the 55th minute.

Allardyce though maintained that the defeat was all down to the assistant referee.

He said: “It is one of those decisions I wouldn’t mind getting myself into trouble with to be honest. But unfortunately that would cost me money and I don’t want to part with my money when I don’t deserve to be parted with it.

“You can’t say what you really think. But it hurts deeply – not just for me but the players in particular. A result has been taken away from us by no fault of our own – by an assistant referee that has got a horrible decision wrong.

“We have to take that on the chin, it can’t be changed. We have to accept that disappointment but look at the positive side of the performance and continue by trying to get three points against Manchester City.

“You have to complain more when a decision like this is made and it has cost us a crucial result. We have had a poor Christmas and that point would have made us feel that much better.

“The players played very well and we took the game to Chelsea, particularly in the second half. We created some good opportunities and took one. We could have taken more of them and got something out of the game, even with that decision from the linesman.

“It is the worst decision I’ve had go against me this year – no question about that. From our point of view it is difficult to take but he can’t hide from it. It can only have been his fear maybe – blind fear in terms that he had to make crucial decision at a particular time on Chelsea’s home ground. But we can do nothing about that now.”

Allardyce remains convinced the only way to prevent such controversy in the future is the introduction of technology.

He added: “I’ve been an advocate of it for years. The game is so finally balanced now and we are living in a more volatile world in the Premier League than ever before.

“These decisions put more pressure on you as a manager when results are not going in your favour. I wouldn’t know where offside is now. The offside rule has perhaps thrown far too much pressure on assistant referees and referees themselves.

“This one was blatant offside. There is no argument about interference or non-interference. It has come off a Chelsea player and the other Chelsea player is two yards offside at least. The assistant referee is in a good line and there is only a blue shirt between our goalkeeper and the goal but the flag didn’t go up.

“But video evidence is something that should have been introduced years ago. It makes life easier for everyone involved and stops the controversy that surrounds major decisions like that coming out after a game when you have been hard done by. The technology should be used in a positive way.”

Chelsea manager Avram Grant refused to condemn the fans who chanted: ’You don’t know what you’re doing’ at him during the second half.

The home fans were unhappy with his substitutions as they toiled to overcome Newcastle. Grant was abused and booed when he replaced Joe Cole and Michael Ballack with Claudio Pizarro and Scott Sinclair.

It was the first time he had been targeted by the boo-boys since taking over Jose Mourinho in September. Neither did he have any views about Kalou’s controversial winner – claiming he had yet to see a TV replay of it.

But Grant said: “I have not seen the television but we created so many chances today so we deserved to win anyway. We created eight or 10 good chances.

“I think the supporters are behind us. They know we are not having an easy time with all the problems we have. We continue to fight but it is not easy.

“This is the time to speak about the players who played. They showed good football in the first half and a lot of character at the end of the game.

“The substitutions were made because Joe Cole had an injury and Michael Ballack has not played so many games, but we needed him because of the injuries. We can cause him a problem if we let him play for 90 minutes at the moment. But I will not be pessimistic today.”
