​Former Chelsea striker Diego Costa regrets the manner in which he had to leave the Premier League champions as he admitted that he had 'special affection' for the club and the fans.

The 28-year-old finally left the Blues and landed in Madrid on Friday to complete a transfer to his former club. The Spaniard won two Premier League titles in his three years spent at the Stamford Bridge.

Although, his Chelsea career virtually ended the moment Antonio Conte texted him that the Italian manager doesn't consider Costa as part of his plans before the current season. Speaking to ​Marca, Diego said, "Atletico Madrid is my home and here I am. I am very happy."

He continued by stating the length of his transfer negotiation as he said, "[The negotiations] went on too long, but there was a happy ending in the end. Now I'm waiting to see my teammates and to train."

The Spanish striker then spoke about Chelsea and showered his affection for the Bridge as he said, "I don't want to have an ungrateful attitude towards Chelsea, because I was also very happy there and played in a great team. I didn't want [my departure] to unfold as it did."

He concluded by hailing Chelsea football club as he said, "I have a special affection for the people at Chelsea."

Since Costa's exodus from Chelsea, the Blues have gone on to sign a replacement in the shape of Alvaro Morata who has hit the ground running in the Premier League already this season
