The Danish manager believes that the Swans will need to spend this summer to avoid going backwards as he plans for the Capital One Cup winners' first Europa League campaign.
Having led the Swans to Capital One Cup glory in February, Laudrup is seeking a big enough transfer budget from the board to enable him to prepare adequately for the dual challenge of Premier League and Europa League campaigns.
"At this club we cannot pretend to think that we are going to win another major trophy next year or even the year after that because that will be very difficult," Laudrup told reporters. "However, if we're talking about the Premier League, I think we will have to improve just to stay where we are now.
"It will be very, very tough to stay in mid-table, because some of the other clubs below us want to invest to improve."
