Diego Costa says he only has good memories of his time at Chelsea, having been officially unveiled as a Atletico Madrid player.

The Spaniard, who agreed a deal to leave Stamford Bridge following the summer window and during Atleti’s transfer embargo, is once more registered under Diego Simeone.

Despite a rather public falling out with Blues boss Antonio Conte, following their Premier League title triumph last season, Costa insists he enjoyed his time in west London.

"I learned English there," the striker joked when asked what his time at the club was like.

"Seriously, the supporters, the people at the club and my teammates helped me a lot.

"Chelsea is a great club and I only have good memories.

"I've been waiting for this moment for a long time," the Spain international went on to tell reporters at his unveiling, having not played all season.

"I just want to get in shape to play as soon as possible, I'm tired of training.

"You can tell I've already worked and prepared well to play, I'm here to help the team and score goals.

"Atleti are not in the Champions League now, but we are going to fight for what we have left."

"I need to play," he added.

"As a bystander, I suffered more than as a player."
