Diego Costa has revealed he wanted to seal a return move to Atletico Madrid last summer.
The Brazilian, who has scored 17 goals in 26 Premier League games this season for the Blues, was eager to return to his former club but talks with Rojiblancos never materialised so he had to continue plying his trade with Antonio Conte's Blues.
Speaking to El Larguero, he said: "Atletico knows I have a special feeling for the team, I lived the best moment of my career there. El Cholo [Diego Simeone] knows it wasn't impossible for me to come back to Atletico.
"The relationship with Conte didn't start well because when he arrived I told him I wanted to go to Atletico. Chelsea's fans love me a lot, even more than in Atletico, figure that!
"When Atletico had to wait for me they didn't, there was still a month to go in the transfer market.

"I've done everything to come back to Atletico Madrid but I wouldn't fight the same to return. When Atletico didn't wait for me, I had to go to Conte with the tail between my legs."
Regarding leaving Chelsea again in January when a reported £30m-a-year offer was made by a Chinese Premier League side, the former Atleti frontman said: "In life, anything can happen and I do not close the door to anything. In football you are worth what you are worth when you are good.
"And why not? But right now I am good at Chelsea…I have two years left on my contract and I intend to fulfil them.
"But you never know. It's not impossible to reject it because there are things to assess. You have to think about it all. I do not rule out anything. If they come with something for Chelsea and the club tell me to go…I can go to China or elsewhere."
