The Swans face Fulham on Sunday in the final game of what has been a successful season, during which they have won the Capital One Cup and secured a top-10 finish in the Premier League.
Laudrup has promised there will be plenty of new additions for next season, with a striker top of his wish list.
However, he is also being realistic with regard to the players he can bring in on the budget he has available to him.
"There is an understanding of the players we want, the board know we need to strengthen the squad just to stay where we are," said Laudrup. "The teams below us in the table will spend heavily to try and get to where we are.
"The names we are talking about, some of them are not expensive, we are not going to sign (Sergio) Aguero or (Luis) Suarez.
"But we have to do it quickly and almost secretly because the moment other clubs in the Premier League get a feeling Swansea are going for a player they might decide they want him as well and that makes it difficult for us.
"We need to strengthen in different positions. I don't want to go into details, but it is no secret I think we need some alternatives for scoring goals.
"But if none of our regular players leave then I think there will be between five or seven players coming in."
Laudrup is also hopeful of keeping hold of his best players, including Michu, who was rewarded for scoring 22 goals in his debut season by being named the club's player of the season.
"It was not really a surprise to see him win the award, was it?" added Laudrup.
"He has scored over 20 goals and without him we would be struggling. Goals are so important, goals are what get you points and points are vital.
"It is so difficult what players like him can do, to arrive late in the box.
"That is so difficult to mark, look at (Frank) Lampard, (Steven) Gerrard, how many goals come when they arrive in the box? A player who can do that is worth a lot."
