La Blaugrana have grown frustrated by the ongoing transfer gridlock between the two sides for the French international and they have reduced their previous valuation of the 31-year-old.
Griezmann returned to Madrid at the start of the 2021/22 season as part of a two year loan deal with Los Rojiblancos.
The initial agreement included a high profile purchase clause of €35-40m, which needed to be activated by the end of the season, with the option becoming mandatory, if Griezmann played in more than 50% of games.
That loophole has been ruthlessly exploited by Atletico in the opening months of 2022/23 with Diego Simeone bringing him on as a late substitute, to avoid being classed as an appearance.
According to reports from Marca, Barcelona are now ready to sign off on a €20m deal, plus variables, with Griezmann taking a pay cut to complete the move.
