The France international has enjoyed a magnificent season in Spain this year, scoring 32 goals in 53 appearances.
The winger’s form has sparked enquiries from Chelsea and Manchester United, who are both keen on signing him this summer.
The Premier League pair’s interest had led to claims Griezmann had penned a new deal with Atletico to clear up his future.
But now the Frenchman’s football adviser Eric Olhats, who has known Griezmann since he was 14, has denied talk of a new contract and instead revealed there are other offers on the table.
“Contrary to certain claims announcing that Antoine at Atletico next season will be the case without fail, nothing has been decided or endorsed,” Olhats told L’Equipe.
“We are currently listening to different clubs who also offer real interest and attraction.”
