Antoine Griezmann trained with his new teammates on Sunday after being officially unveiled as a Barcelona player.
The French striker, 28, took part in a training session at Barca's Joan Gamper training ground alongside the likes of Samuel Umtiti, Ousmane Dembele and Ivan Raktic after completing his €120 million (Dh497m) transfer from La Liga rivals Atletico Madrid.
During a presentation to the media at Camp Nou, Griezmann described Atletico's angry response to his departure - the club have accused both Griezmann and Barca of agreeing a transfer in March but waiting until his release clause dropped below €200m at the start of July - as "a pity".
"I went to see them on purpose so they would not be caught off guard and could prepare for the future," Griezmann told a news conference.
"We reached an agreement but finally it changed, it's like that, you have to accept it," he added when asked about Atletico's response.
