Former Chelsea striker Diego Costa was finally unveiled as an Atletico player three months after re-signing for the La Liga giants and could play as early as this week.
Costa, 29, has been unable to play for Atletico Madrid due to a transfer ban they were serving.
Costa was officially presented at the Wanda Metropolitano stadium on Sunday, alongside fellow Spain team mate Vitolo, who signed from Sevilla in July.
He then took part in an open training session, which local media said was attended by 20,000 supporters.
“I’ve waited a long time for this day, I’m tired of training and I need to play,” Costa said on Sunday.
When asked what his time at the Blues was like, he laughed: “I learned English there.
“Seriously, the supporters, the people at the club and my team-mates helped me a lot.
“Chelsea is a great club and I only have good memories.”
“Atleti are not in the Champions League now, but we are going to fight for what we have left.”
“You can tell I’ve already worked and prepared well to play, I’m here to help the team and score goals.

Atletico Madrid have been under a transfer ban for the past two windows after being found guilty of breaching rules over the transfer of foreign players under 18.
But the ban expires on 1 January meaning Costa could make his debut on Wednesday, with his first league appearance set for Saturday at home to Getafe.
