Swansea City are aware of transfer interest for star attacker Michu.

The Sun says Michu is wanted by Serie A duo Napoli and Genoa.

The Swans warn it will take a king's ransom to wrest the Spaniard, 26, away. But a Napoli insider said: "Italian clubs have asked about Michu and demanded details about his situation.

"A player that can score 10 times in the Premier League will interest any big club."

Michu only cost £2million from Rayo Vallecano. And Swansea No 2 Alan Curtis said: "I'm confident if there are any bids we'll fend them off."
