Barcelona was interested in the Frenchman, but he decided to stay at Atletico Madrid.
He thought it was meant to move, however, a video came out after explaining his decision to stay in the Spanish capital.
The Messi is undoubtedly the largest player in the world, and many report that he is the main decision maker in Barcelona.
And Griezman has admitted that, knowing that he would not be a star person in Nou Camp, he played his own choices.
"Was it hard for Barca to give up? It was very difficult," Griezmann told Canal Plus.
"You have Barca who wants to call you who sends the messages.
"But then there's a club where you are, where you are an important player and where they make up your project around you.
"[And] in the unconscious, perhaps Messi's lieutenant.
"But my teammates and people in the club [Atleti] they did everything, they came to speak to me, they increased the salary.
"They did everything to show that it was my house and that I should not leave.
"It was really difficult times, especially for my wife, where I awoke at 3am to talk about it!"
Many have cut Griezmann this year to Ballon d'Or, with Lionel Messi also a rival.
Griezmann has won the World Champion on his side as he has won the final and won the bronze ball for being the third best player in the tournament.
And he recently admitted that he thinks he should have at least three main gongs.
"Comparing 2016 and this year, I have to be in the first third," said Griezman L & # 39; Equipe.
"In 2016, I lost two finals and was in the first third place. This time I won three finals.
"It would not be unfair, but I'd be wondering what else I could do. I've won three trophies, broke out at crucial moments, but I have not voted.
"I think about it, especially since the closer I get to it. The Ballon d & # 39; Or is a prestigious prize, and it's the highest, you can play as a player."
