"We carry on with the intention of winning the games we have left and staying competitive", he told a press conference ahead of Wednesday's visit of Villarreal.
Barca have emerged as favourites to sign the France worldwide and are reportedly willing to meet his £88m release clause, with club president Josep Maria Bartomeu revealing earlier this week that he has already spoken to the player's agent.
Griezmann has a £88m (€100m) release clause in his contract at the Wanda Metropolitano.
Cadena Cope claimed on Tuesday that Barca have already told Atletico of their plans to pay the €100 million fee which would allow them to bring the France forward to Camp Nou. "He is very young and we expect a lot of things from him".
The attacker has a chance to win silverware with his current employers if Atletico can defeat Marseille in this season's Europa League final.
He said Atletico would be demanding compensation from Barcelnoa should "the player exercised his right to nullify his contract due to their pressure throughout the season".

"At the same time, I let him know that his inappropriate conduct was against the integrity of the competition".
Barca manager Ernesto Valverde tried to play down the rumours, but he also couldn't resist talking up Griezmann's quality, per Goal's Matt Dorman: "He's a great player, I have no doubt about that. I hope this statement serves its objective and that us Atletico fans can enjoy this moment and prepare ourselves for a final like we should".
The manager was also asked about the France worldwide joining Atletico president Enrique Cerezo for lunch on Tuesday - with the meeting being perceived as one in which the player's future was discussed - but he brushed it off.
Griezmann was linked with a move to Manchester United last summer before he committed his future to Atletico.
"I can not tell you anything else because I do not know anything else".
