Swansea manager Michael Laudrup has suggested clubs will have to part with up to £30 million to secure the services of Michu.
Michu, 26, has been one of the signings of the season so far, costing the Swans just £2 million in the summer, while having already hit 11 goals for the club.
The former Real Vallecano man’s form has led to speculation linking the forward with a move away from south Wales in January, but Laudrup has warned any club thinking about making an approach that they will have to pay a hefty fee.
“I don't want to let him go, sometimes the offer can be so big you have to accept but I really don't think clubs are going to pay so much money for him,” he said.
“We have the example of what Liverpool paid for Joe Allen, if they have to pay double for Michu there are few clubs who could afford that. Joe went to Liverpool and you know more or less what they paid for him, but a guy who has scored many goals must be worth a lot more, so you work out the figures.
“I don't think anyone will come with that money so he will stay here.''
Swansea’s recent impressive displays, including a 2-0 win against Arsenal last weekend, has moved the club up to seventh in the table, leading to some fans dreaming about a place in Europe next season.
Laudrup, however, is not getting ahead of himself and is eager to play down expectations, insisting there is still a long way to go.
“There are other teams who will fight for that, it would not be logical for a team like Swansea to play for such places,” he said. “That does not mean we are not happy at being at a good place in the table, but I look at the points.
“I am pleased with what we have now, but if we are sixth, eighth or tenth now it is not so important. We are 15 games in, there are 23 to go and it is still tight. If you look at the teams above and below it is very tight and you know in three or four games the situation can change very quickly. So we need to take one game at a time and when we get to March or April then we can see what happens.''
Laudrup is likely to again be without Pablo Hernandez for Swansea’s fixture with Norwich on Saturday as the winger struggles with a muscle injury. Goalkeeper Michel Vorm is back in training after a groin problem but is not likely to be risked with deputy Gerhard Tremmel having filled in well.
