Manchester United manager Sir Alex Ferguson insists Ruud van Nistelrooy and Roy Keane are not leaving the club. Van Nistelrooy has been linked with Real Madrid, while veteran captain Keane is a reported target for Celtic. But the pair appeared alongside Ferguson in a show of unity at the Carrington training complex on Friday. And Ferguson said: "Things have become silly and dangerous in the last two weeks. There is no foundation to the gossip that they are leaving." It was claimed Van Nistelrooy had been involved in a row with Ferguson, while it was also reported the Old Trafford boss was unhappy with Keane's decision to revive his Republic of Ireland career. But Ferguson said: "I think it is important that it comes straight from everyone involved. "As far as Ruud is concerned, we wanted to clarify whether he is going to Barcelona, Real Madrid or whether he is staying here. We are clear in our mind about that. "Things have become silly and dangerous in the last two weeks "Roy is the same. There has been speculation that he is going to Celtic, that he has had a massive bust-up with me and that the Irish situation has been a problem. "It hasn't been and It's important to clear this up." Van Nistelrooy has been linked with Real Madrid and Barcelona but the Dutch striker, who will return to the United line-up for Saturday's game with Blackburn, insisted he is going nowhere. "I signed a new contract in January and I said in the past I am going nowhere. "I want to stay and be part of the club over the next four years and I will keep reminding everybody that is the case. "This was a good day to come out and show the fans what the real situation is. That is it." It is a bit worrying as the transfer talk seems to be going the say way as the Becks saga last season United chief executive David Gill has insisted Van Nistelrooy was staying when he said:"We have already said he is not for sale. "The facts of the situation are the same as they were a week, two weeks, three weeks, four weeks ago. "We've signed Ruud on a long contract, and that wasn't done lightly or without planning. "He has another four-and-a-half years here. That is fact. There is no point saying anything else."
