Tim Cahill revealed that he stopped himself celebrating his FA Cup winner because it was against his old club Millwall.
The Aussie midfielder scrambled in the second-half clincher that sends Everton into a fourth-round home tie with Chelsea and ends the dreams of his former club for another season.
Cahill helped Millwall to the FA Cup final two seasons ago and secured his move to Everton on the back of that famous run.
Now he is fully aware that being the architect of the Toffees' 1-0 replay win last night is something he should not be gloating about.
Cahill said: 'You can get carried away with celebrations, for a moment I had a thought and decided not to go mad and just pay my respects to the club that gave me my start in the game.
'To celebrate would have been a kick in the teeth, it is all about respect.
'Whoever scored was going to win the game, they were in our faces and made life difficult but we had to get on top of them and when we did it all paid off.
'I'm scoring yes, but goals are goals and as long as we are winning and I am in the first-team shirt, that's all that matters.'
Cahill won praise for his restraint from Everton assistant boss Alan Irvine, who said: 'The script was written for Tim, even though he didn't celebrate too much.
'The initial reaction is to celebrate when you score, but because he has respect for Millwall he was very restrained.
'He certainly wasn't running to the corner flag to practice his new routine!
'That clearly said to Millwall that he appreciates what the club have done for him.'
Irvine also insisted that the winner was Cahill's goal despite the close attention of Alan Dunne in the final scramble.
He added: 'As far as we are concerned it was his goal, certainly Tim thinks so. I have watched a few re-runs and I think it was his goal, he certainly looked to get the last touch.'
So Everton will now host the runaway Premiership leaders and Irvine said: 'We are now looking forward to playing Chelsea next, it is the sort of game that you come into football to be involved in.
'And we have another easy one against Arsenal on Saturday! But it is a good time for us to be playing them because we have been going very well, that's five undefeated now.
'We are trying to build on that and we are feeling pretty good about ourselves at the moment.
'We are creating chances, we just need to be more ruthless when we get them.'
Millwall boss Dave Tuttle saw his side lose for only the second time in his seven matches in control.
He said: 'We did well to contain Everton and looked reasonably solid defensively without having much penetration in the final third.
'That has been the story for us for much of the season. The priority now is staying in the Championship.
'We are very disappointed at going out of the FA Cup but I have no complaints about the result or the players, who gave everything that they had.
'They did well up against a good Premiership team over two games.'
