Manchester City manager Roberto Mancini believes Carlos Tevez will have the right mindset on Wednesday when he returns to Old Trafford in the Carling Cup semi-final second leg.
City hold a 2-1 advantage thanks to a brace from the Argentina striker, who was involved in touchline spat with former Manchester United team-mate Gary Neville following his opener.
Tevez then described the United captain as an "idiot" and a "boot-licker" after the first leg.
Mancini has now tried to take the heat out of the situation and told Tevez not to make further remarks about Neville.
He said: "I think Carlos will be calm in the next game against United. He will think only of how he is playing and how the team is doing.
"I think these things (Tevez's comments) can sometimes happen after a match.
"The players are tired and sometimes they do not think what they are saying.
"It is important that this matter is finished now as we need to focus on our next game."
Mancini sidestepped questions about the club becoming "the biggest and best in the world".
The remarks were apparently made by chief executive Garry Cook at a fans forum in New York.
According to Sky Sports News, Cook said: "This football club is, without doubt, going to be the biggest and best football club in the world.
"I will make no excuses for saying it, as I truly believe it - with the resources and capabilities we have."
Mancini's ambition, for the moment, stretches only in breaking into the elite in England and bringing silverware to Eastlands.
He said: "We have a big possibility. But we must work well in the next month as we want to arrive in the top four.
"We have some problems with injury but in the future Manchester City can be a good team."
Next up are Coca-Cola Championship side Scunthorpe in the FA Cup on Sunday and Mancini has told his side to be on their guard.
He hopes his team do not go the way of Manchester United and Liverpool, who lost to lower league teams in the last round.
Mancini added: "I know City beat Scunthorpe in the Carling Cup but we need to have the right mentality.
"It will be difficult on a small pitch and they will be strong. I have seen Scunthorpe on video.
"The FA Cup is important to us and we want to progress. We must remember what happened to Liverpool against Reading and Manchester United against Leeds."
Midfielder Stephen Ireland is likely to return to the team after being on the bench in midweek following his recovery from injury.
Roque Santa Cruz and recent signing Patrick Vieira are both sidelined with calf injuries.
