Manchester United boss Louis van Gaal has made it clear that he won't enter into deals in the January transfer window just for the sake of making one.

The Dutchman has successfully lured free-agent Victor Valdes to join him at Old Trafford, and signings of the like is what the former FC Barcelona overseer would want to seal because it boosts the quality of his squad.

"When I cannot improve my selection, then I wait," he told ManUtd.com.

"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."

He emphasised that a player's price-tag will not always determine the success of the team he lands on.

"When we can buy a player who can improve my selection, the club shall buy," he continued.

"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."

Meanwhile, the 63-year-old is confident that he will be able to guide the Red Devils back to glory that has been lost when Alex Ferguson stepped down.

"Now that I coach Manchester United, I expect more attacking quality," he added.

"If it is not this year, then next season or the season after that. We shall improve and you shall see it."
