Nemanja Vidic has pledged his long-term future to Manchester United, according to chief executive David Gill.
The Serbia defender's current deal is up in two years time, but an extension to his contract has been agreed by both parties.
Vidic has been linked with a move away from Old Trafford but he is now staying at the club.
Gill said: “I am very pleased to confirm that we have agreed terms with Nemanja on a new long-term deal with the club.”
Vidic's decision to stay is a huge boost for United given Rio Ferdinand's fitness problems.
While the length of the contract extension has not been disclosed, Gill believes Vidic will put pen to paper next month.
Gill said: “We sat down with Nemanja and his advisor at the end of last season and started discussions. They broke up when Nemanja went away to the World Cup, but resumed when Serbia were knocked out.
“It's yet to be signed — the paperwork is now being sorted by our lawyers and being checked by Nemanja's advisors. He's still away on holiday, but the plan is that when he gets back the papers will be signed.
“We've shaken hands on it and we're confident it will all be signed and sealed in early August.
“It's great news for Manchester United and great news for Nemanja and the fans.
“There was a lot of speculation about Nemanja's future, but in my view it's been the media drumming some old stories.
“They certainly didn't come out of the Manchester United camp and I'm confident they didn't come out of Nemanja's camp.”
Gill also intends discussing a new contract with Rooney.
Like Vidic, the England striker still has two years to run on his current deal.
Rooney scored 34 goals in all competitions last season, but despite his efforts the club surrendered their Barclays Premier League crown to Chelsea.
Gill said: “The current intention is to meet with Wayne and his advisors when we're back from tour and he's back from holiday with a view to sorting out a new deal for him.
“It's clear from what he has said and what the club have said that both parties are very keen to sort things out and secure his long-term future at United.
“Given his desires and what he means to the club we're very confident that can be achieved.”
Meanwhile, striker Danny Welbeck accepts he is likely to go out on-loan to a Premier League club in the coming season.
Manager Sir Alex Ferguson says both Welbeck and midfielder Tom Cleverley have good futures, but need regular football at another top-flight team.
Sunderland have expressed an interest in Welbeck, who had a spell on-loan at Preston last season before suffering a knee injury, which needed an operation.
He has made a bright start to United's five-match summer tour which takes in Canada, the United States and Mexico.
The 19-year-old scored in the victory against Celtic in Toronto last week and followed that display by setting up Gabriel Obertan for the winner in midweek when Philadelphia Union were beaten.
Welbeck said: “My main aim is to be part of the first team set-up, but I am happy to go on-loan if the manager wants me to. I just want to keep playing games and improving.
“I feel I have improved a lot over the last couple of years in particular. I have learned so much during that time particularly the
importance of mental strength on and off the pitch. I just want to keep improving and striving to show everyone what I can do.
“I am really pleased with how the tour has gone for me so far and I am happy with my performances. I have got to keep going and continue to get my fitness up.”
Welbeck says it is a “privilege” to be around senior players like Ryan Giggs and Paul Scholes on tour. The squad are due to leave Philadelphia for Kansas today to prepare for the match against the Wizards tomorrow.
Welbeck added: “It is always good to be away with a few of the older lads because you pick up so much from them every day.
“You see how they prepare for games, how they rest and how they train. They are unbelievable — they have this huge determination to win every single training match, let alone actual games. Just to be around them is a real privilege.”
The Wizards are expecting a bumper crowd at the Arrowhead Stadium with ticket sales still climbing after hitting the 40,000 mark last month.
President Robb Heineman said: “I am hopeful we are going to have the largest crowd on the tour. This match speaks volumes for the momentum we have in Kansas City.”
United face an MLS All-Stars XI in Houston before ending the tour in Guadalajara against Chivas.
