Chelsea's chances of keeping Diego Costa at Stamford Bridge have improved, with Atletico Madrid president Enrique Cerezo seemingly giving up on re-signing the player at the Vicente Calderon. This follows the Spanish striker admitting he is "finally happy" in London earlier this week, having enjoyed an impressive start to the season under new boss Antonio Conte.

Costa moved to Chelsea in the summer of 2014 following a stunning campaign with Real Madrid, committing his future to the Blues with a five-year contract. However, he has been regularly linked with a return to Diego Simeone's side in recent windows having admitted his failure to adapt to London's way of life.

AS reported during the summer that Atletico Madrid had launched a €60m (£52.7m, $67.2m) to convince Chelsea to part ways with the player. After seeing their approach rebuffed they signed Kevin Gameiro from Sevilla instead.

Simeone has since publicly admitted Costa was his first choice to partner Antoine Griezmann, while the Spaniard himself revealed last month he wanted a return to his homeland.

"We all know that there was a possibility to return to Atletico Madrid but it couldn't happen due to some details. I would like to thank the people from Atletico and especially El Cholo (Simeone) because they always placed confidence in me," Costa said last month.

Both Atletico and Costa have enjoyed good starts to the new campaign. Simeone's boys currently lead La Liga ahead of Real Madrid and Barcelona, while Costa tops the Premier League scoring charts with six goals in his first seven games.

Costa now admits he is acclimatising to London.

"I liked Madrid a lot and have some very happy memories there but I am happy in London now," Costa told reporters from the Spanish national team's camp. "I always follow Atletico and watch what they're doing – they're really strong at the moment and I am so happy for them. Atletico have been at this level for quite a few years now – battling for every trophy and beating the best sides, they definitely deserve it."

Club president Cerezo has now added he believes the Spaniard will remain at Conte's side until the end of his contract, as the Blues are reluctant to negotiate the departure of the Premier League top scorer at any price.

Asked whether Atletico will try to make a new attempt to sign the Spaniard in the future, he said, as quoted by AS: "Costa has a contract at Chelsea and I guess that Chelsea are not stupid and will not let him go."
