Atletico Madrid's director of football has moved to deny rumours that striker Diego Costa could be on his way to either Arsenal or Chelsea in the January transfer window.
The Brazilian-born forward has been in stunning form so far this season, and has 19 goals in 17 La Liga games.
That puts him above the likes of Cristiano Ronaldo and Lionel Messi as La Liga's top scorer - and has attracted the likes of both Chelsea and Arsenal.
According to some reports, the Premier League giants will try to lure the 25-year-old from the Vicente Calderon when the winter window opens.
However Atleti chief Jose Luis Caminero told Spanish newspaper Marca that Arsenal and Chelsea doomed to fail if they try and land the forward in January.
"Right now Costa does not think of leaving, he is contracted to Atletico," he said.
"He has renewed with us which is important. He has shown that he wants to continue at this club."
Both Premier League clubs are in need of reinforcements in attack and are likely to use the Janaury window to bring in a new striker.
Arsenal have little to offer in attack behind main man Olivier Giroud, while Chelsea's strikers failed to fire yet again as they ground out a 1-0 win over Swansea yesterday.
Jose Mourinho has three main strikers at Stamford Bridge - Fernando Torres, Samuel Eto'o and Demba Ba - but that trio have mustered five Premier League goals between them this term.
Costa is believed to have a £32 million release clause written into his contract, although Arsenal are said to be unwilling to pay that much for his services. Chelsea would have no issue with forking out a sum of that size.
