Sam Allardyce insists it will be business as usual for his side, as West Ham United travel to Goodison Park in what will be David Moyes' final home game in charge of Everton.
While Big Sam fully expects it to be a momentous occasion for his opposite number, he doesn't foresee any let-up from the high-flying Toffees.
As for Moyes' appointment as Manchester United manager, the Hammers boss reckons he is the ideal man to succeed Sir Alex Ferguson, even if it takes time to acclimatise.
It's going to be a strange atmosphere on Sunday. What do you think it will be like?
SA: "I don't know quite how it's going to be to be honest with you. I suppose that it's a difficult situation, albeit not for us. We'll go into the game as professional as ever wanting to try and, if we can, claim three points at Everton.
"In terms of the last home game of David's reign as Everton manager, it will be an emotional affair for him. But I'm sure, knowing David as well as I do, that he'll be professional enough and calm enough to control his emotions and do his very best to prepare the team to go and win. So I don't expect any favours whatsoever.
"I would have thought and hoped from his point of view that the crowd appreciate what he has done and show their appreciation. At the end of the day, it's an enormous move for him and his career has gone to the next level. For what he has done at Everton over the last eleven years, I don't think anyone can do anything other than applaud him."
Were you surprised that Sir Alex Ferguson himself recommended David Moyes to the Manchester United board?
SA: "I'm not surprised. Apart from his talent as a manager, I think it's his stability that he's shown at Everton. Manchester United need to move on and try to establish the same sort of stability Sir Alex has given them over the last 27 years. I think David Moyes is a perfect candidate to try and emulate what Sir Alex has done, which will be the hardest job he has ever faced.
Having known David for many years, how do you think he will approach it?
SA: "Head on. He'll try to establish his personality and his ideas. I'm sure he'll adjust but not too quickly. I think it's something he'll do relatively slowly and he'll try to move the club forward on the same level that it has been before. It's a huge task for him and the staff that he takes with him. It is one of the biggest jobs in the world of club football, so it's a fantastic opportunity for him."
Were you surprised by the timing of Sir Alex's announcement?
SA: "Having had a few days to look at it, probably not, because it's all timed for the last home game on Sunday, that he's appreciated by the thousands of supporters that turn out at Old Trafford. Not just picking up the Barclays Premier League trophy, but also Sir Alex's last home game. So I suppose from that point of view, that's why it has come out when it as.
"David Moyes has done eleven years at Everton under very difficult circumstances and managed to secure his position there in this volatile industry of ours. I'm sure David will see this as the final move of his career, he hasn't had many. In longevity terms, as long as he wins trophies at Manchester United David Moyes will stay there."
