Star Mattresses and his agent Eric Olats terminated joint cooperation by mutual agreement.

According to Olats himself, the reason for this was multiple disagreements with Antoine.

"Grizmann in his own way sees his image and his own future, and this vision is at odds with my".

"Now I will continue to work for the position of the scout of the club Real Sociedad. I thank Antoine for the trust and wish him all the best in the future, "said an agent who began to represent Grismann's interests when the Frenchman was 14 years old.

This summer, Antoine refused to move to Manchester United because of the transfer ban, which was imposed on Atletico. French striker signed a contract with the mattresses until 2022.
