The Premier Leagues top clubs have been put on alert after Swansea manager Michael Laudrup admitted that he doesn't know what the future holds for Michu, according to FourFourTwo.
Arsenal have shown interest in the Spaniard who has been a revelation in England since moving to Swansea from Rayo Vallecano last season.
Regarded as one of the best bargains ever, Michu cost just £2 million- peanuts by todays football standards.
It is expected that just two years later the Swans could demand anything up to £30 million for their play-maker.
The attacking midfielder has scored 21 Premier League goals from 41 games and has been called up for Spain but hasn't turned out for the world champions.
Laudrup said: "The most important thing in all this is what the player wants,"
"Michu wants to stay. He wanted to stay after his first season because he wanted to take part in the second year with Europe and everything.
"What happens in the future? I don't know but I think it's so important what the player wants and I don't think Michu had any doubts whatsoever that he wanted to stay here this season, but then what happens next year no one knows.
"I don't look at him as just a goalscorer because for me he's not even a centre forward,"
"He's an offensive midfielder who can score goals and can play as a forward, so I don't have that picture of if he hasn't scored for three games it's a problem.
"He's a very, very important player because he scores goals and sometimes he makes those runs where you think he's wasting energy but he's doing it for the rest of the team to follow."
Laudrup bought Wilfried Bony over the summer to take some of the goal-scoring pressure off the 27-year-old.
So far this season the League Cup holders are ninth after five Premier League games and recorded an incredible 3-0 victory against Spanish giants Valencia in the Europa League last week.
