Manchester United manager Louis van Gaal has revealed that he will only sign a player this month if they will definitely improve the quality of his squad.
United have been linked with several players, including Mats Hummels and Nathaniel Clyne, and have already sealed a move for free-agent keeper Victor Valdes.
However, the Dutchman is adamant that he will not be pressed into spending money this January, unless a player of the highest talent becomes available.
He told reporters: "When I cannot improve my selection, then I wait. And then I maybe have to wait a year more. Maybe you think that there are so many fantastic players, but it is not like that.
"However, I don't [necessarily] prefer to wait until the summer when I can improve my selections. That I have showed with Valdes.
"When we can buy a player who can improve my selection, the club shall buy. Money is not interesting. It is always quality of the players in comparison with the other players that I have. I have to compare. I have to decide. Money doesn't play any role."
Van Gaal has indicated that the arrival of Valdes will not put David de Gea's place as first-choice keeper under threat.
