Both Arsenal and Liverpool are believed to be interested in signing Spain striker Michu, according to the Daily Express.
The Swansea hitman was called into Vicente del Bosque’s Spanish squad this week and the Premier League pair have been informed they would need to stump up over €30m for his services.
Swans’ boss Michael Laudrup, who signed the 27-year-old from Rayo Vallecano for a reported €2.2m in July 2012, had previously insisted Michu is worth at least €30m after an impressive debut season when he scored 18 goals from 35 appearances in the English top flight.
It is a valuation Swansea Chairman Huw Jenkins this week said he agreed with.
“We've seen with Tottenham and Gareth Bale that every player has a price. We are not in that bracket with Tottenham but they sold a top player. We are realistic about that side of things.
"I would say Michael was about right with his valuation of Michu if you look at the current market, but this call-up enhances that further.
"We know we have a very talented player and naturally we want to keep him.”
It is understood that Arsenal boss Arsene Wenger along with Brendan Rodgers at Liverpool are continuing to keep an eye on the player’s rapid progression, but it would take a bid of massive bid from either to tempt the Welsh club to part with their star man.
