Swansea boss Michael Laudrup hails £2m Michu as 'the bargain of the season' and believes there is no danger of the Spaniard leaving the Liberty Stadium as few teams can afford him.
Michu's latest performance put the Swans in sight of their first major Wembley final, scoring the first goal of their 2-0 win at Chelsea in the first leg of their Capital One Cup semi-final.
Laudrup showered praise on the 26-year-old following their Stamford Bridge win, and said while he couldn't put a prize on the number nine, only a handful of teams could now afford him.
"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," he 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."
Michu's goal on Wednesday marked his 16th since being recruited from Rayo Vallecano last summer, and while Laudrup is said to have been alone among Premier League coaches and scouts in recognising his potential, the Spaniard has certainly caught everyone's attention this season.
Asked about enquiries for Michu, Laudrup 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.
"Bayern Munich in Germany so really there is only few, few clubs and Michu likes it here.
"He's happy with the team where he is so I'm really not afraid that something is going to happen because I'm so sure he will stay with us for the next five or six months.
"I don't know in the summer, but still I can't really see who could sign him. I don't know how much he's worth. Ask my chairman.
"He was the bargain of the season, we know that. But we're happy we've found the right players."
