Chelsea fail in £52m bid for Atletico's Aguero & Godin
Chelsea have had a £52m bid for Atletico Madrid striker Sergio Aguero and defender Diego Godin rejected.
Atletico have also recently rejected a £39m bid for Aguero from Real Madrid.
"Atletico have said no to the two offers because they believe in these two players," said majority shareholder Miguel Angel Gil.
Argentina international Aguero, 22, has scored seven league goals this season, while Uruguay international Godin, 24, has won 43 caps.
"We never comment on transfer speculation, no matter how wild it is," said a Chelsea spokesman.
Aguero, whose father-in-law is Argentina legend Diego Maradona, joined the Spanish side from Independiente for a club record fee of £20m in 2006, while Godin joined the Madrid club from Villarreal in August 2010.
As well as failing in their joint bid for Aguero and Godin, Chelsea are thought to have been unsuccessful with a £17m bid for Benfica defender David Luiz in December.
However Chelsea remain hopeful of securing a deal for the 23-year-old Brazil international.
Meanwhile, Atletico have responded to speculation about the future of their coach Quique Sanchez Flores following a run of bad results.
The Europa League holders have been knocked out of this season's competition as well as the Spanish Cup, while on Sunday they lost 1-0 at struggling Sporting Gijon on Sunday to slip 10 points off the Champions League qualification slots.
But Gil told the Atletico website: "Sanchez Flores will be coach until the end of the season.
"At the end of the campaign we will talk."
