Any residual fears that Manchester United's signing of Victor Valdés would pave the way for David De Gea's departure can be temporarily laid to rest, at least according to the Times' James Ducker (£). In his article, United are said to be "confident" that the Spain goalkeeper will imminently sign a "lucrative" deal.
Of course, that doesn't mean that he's going to stay for United forever and ever and ever (though it'd be nice if you did, Dave), but it does mean that Real Madrid will have to pay an awful lot of money if they're going to buy him -- considerably more than they would have with his contract expiring next summer. It means United's negotiating position would be quite a bit stronger than it is at present.
So, it seems like the Valdés signing really was just to add a good backup option. As for Anders Lindegaard, expect to see him leaving Old Trafford in the near future.
