Manchester United say that holding discussions over Roy Keane's future is not an immediate priority for them.
Keane admits he could still stay at Old Trafford
Keane says he thinks he will leave Old Trafford at the end of the season, when his current contract expires.
Assistant boss Carlos Queiroz said: "At this moment we are concentrating on our priorities. The most important is the match with Fulham on Saturday.
"The manager in the right time, the right moment and the right way will address the (Keane) situation."
Queiroz added: "The right way will be in a private and confidential way."
United chief executive David Gill was not available to comment on Keane's future when approached by BBC Sport.
Keane has admitted he could be tempted to stay at Old Trafford if he was offered another year at the club.
He told MUTV: "My contract's up at the end of the season and I don't think United will offer me another one. That's just my gut feeling on this.
"If David Gill rings me tomorrow and offers me another year, then we'll see.
"But I'm not putting a gun to anybody's head and I've never gone looking for new contracts - I've always felt that's up to the club."
Queiroz, who deputised for Sir Alex Ferguson at United's managerial news conference on Friday, admitted it would not be possible for United to replace Keane.
"You don't replace great players like Pele, Maradona, Eusebio or Roy Keane," he said.
"You just create new players in new teams. That is why the game moves forward."
Former United midfielder Phil Neville, who moved to Everton in the summer, paid tribute to Keane.
Neville, who spent 12 years alongside Keane at Old Trafford, said: "If he goes it will be a huge loss for the Premiership.
"If you look at all the greatest games in the Premiership over the last 10 years, more often than not Roy Keane has been in the middle of it all."
He added: "It's news to me, but Roy is one of the best players I have ever played with. You have got to respect his decision whatever decision he makes.
"I'm privileged and proud to have played with such a great captain and someone I regard as a good friend as well.
"He's been the most successful captain Manchester United has probably ever had and he will be missed by the club on and off the pitch."
