Barcelona have been hit with a lot of debts to settle due to the COVID-19 pandemic.
And to do that, the Catalan club are planning of reducing their wage bill by offloading highly paid figures in the squad, a situation that could Griezmann's return to the Wanda Metropolitano Stadium.
The former Real Soceidad man have been struggling to live up to expectations since moving to Barcelona and Simeone having worked with the left-footed forward at Atletico Madrid wants the 30-year-old to do well if he's to remain at Camp Nou.
"I want the best for him and hopefully I can break it in Barcelona. It is an extraordinary club and Antoine is complete.
"After what he gave Atletico, I want him to do well at Barcelona, he is an extraordinary player. At Barcelona, having seasons without being regular for him, he never falls below twenty goals.
"They are important numbers. I hope that he can consolidate the player he has been at the Euros, in the World Cup, in the five years with us. I don’t wish for anything else but him triumphing at Barcelona,” he said.
"I want the best for him and hopefully I can break it in Barcelona. It is an extraordinary club and Antoine is complete.
"In the Eurocup [Euro 2020], he showed again that where they put him he can give a lot of things. But today he is not with us. I want a player who gave me everything to do well,” Simeone added.
"We know each other, we talk with the club, there are positions to improve in the team, we need a forward. Another will come if Griezmann does not come. There the club will decide what is best for the entity’s economy".
