Swansea City boss Michael Laudrup is sweating on Michu's return from injury.
Laudrup said: "I don't know if he will be fit.
"Obviously, he got an injury on his ankle and it was twice the size the other day.
"It's not a muscle injury but it's a question about pain and if he can't put his foot into the boot then he can't play. He can't play in bare feet, I don't think.
"The medical team say it's a possibility he could be fit for Tuesday but let's see."
