It's been suggested Griezmann, who has declared he will leave Atletico Madrid, will arrive at Barca to replace Coutinho.
But a source close to the Brazilian has denied the midfielder is set to make way.
The insider told AS: "It's not true that Griezmann is going to be Philippe's substitute in Barça.
"I do not see why everyone says that. I do not know about the transfer so I do not want to say more, but I can assure you that it is false."
