The Spaniard has proved to be one of the bargains of the season, having scored 16 goals in 25 appearances since joining for £2million from Rayo Vallecano in the summer.
Michu's latest goal set Swansea on course for a 2-0 win at Chelsea on Wednesday night in the first leg of their Capital One Cup semi-final.
Laudrup was full of praise for the 26-year-old after the Stamford Bridge clash and fully expects him to end the campaign as a Swansea player.
"I would never expect a new player to come in and score so many goals, but I can't really say what expectation I had for Michu," the Dane said.
"What he is doing in terms of goals is incredible, especially when you think he's never been a number nine. He's always been a defensive midfielder coming from deeper.
"But against Chelsea he had one chance, one goal. That's a top-class striker. You'd pay a lot of money for that."
Asked about enquiries for Michu, he added: "Well, to be honest, I'm not the one putting the price tag on him.
"We all know the situation - the general economic situation in the world - so there really aren't that many clubs who can buy him.
"There are some here (in England). In Spain there are only two and I think Barcelona and Real Madrid have enough players. Italy, I don't think so. They're trying to sell."
