De Guzman is currently on a season-long long deal from Villarreal, and Laudrup has admitted that he would like to see the Dutch international stay at the Premier League club.
The 48-year-old told reporters: "A lot of clubs are thinking about the end of the season; promotion, relegation etc so they have a lot of important things to think about.
"Jonathan is playing very well and he's scoring goals. But he is happy here and I know he wants to stay here."
The 25-year-old has scored eight goals for Swansea this season.
