Dani Alves' agent claims that his client is attracting interest from more than one famous club on the Old Continent.

The 27-year-old footballer is currently negotiating a new contract with Barcelona, but an agreement has not been reached yet.

Alves' current contract is set to expire in the summer of 2012. According to media reports, London's Chelsea may attempt to acquire him.

"Dani is one of the best defenders in the world, so it is natural that big clubs are interested in him," said agent Joaquinas Macanas.

"We just ask that Barcelona appreciate Alves for his work and improvement over these years."

The player's market value could reach around 30 million euros.
