Barcelona's Antoine Griezmann said previous club Atletico Madrid's irate reaction to his exchange is "a pity."
Griezmann joined Barca this week after the Catalans met his 120m euro (£107m) buyout provision.
Atletico griped Barcelona and Griezmann had arranged the arrangement before the purchase out cost dropped from 200 million euros toward the beginning of July.
"We achieved an understanding yet at last it changed, it resembles that, you need to acknowledge it," Griezmann demanded.
Not long after Griezmann's move was affirmed, Atletico issued an announcement uncovering that they had just "started fitting techniques" to safeguard their "rights and genuine interests".
Reports in the Spanish media throughout the end of the week guaranteed Atletico wanted to go to overseeing body Fifa to contend that Barcelona owe them more than the 120 million euros discharge condition.
Talking at a news meeting to declare him as a Barcelona player, Griezmann, who won the Europa Alliance with Atletico in 2018, stated: "In regards to Atletico, it's a pity. I went to see them deliberately so they would not be found napping and could get ready for what's to come."
