Griezmann, 27, is connected with a move to Barcelona at the end of the season, although the LaLiga winners' pursuit has angered Atletico.
The France worldwide is reported to have a €100 million release clause in his contract, which expires in 2022.
"He has been the most decisive player this season but we have helped him to be like he is".
News of his availability is likely to be considered long and hard by Klopp with the player hugely popular during his time at the club. "It's the truth. It will not affect him because we are not thinking about it".
Griezmann's application has never been in question at Atletico, and he will be desperate to clinch his first piece of silverware for the club in the upcoming final.
He also said, "We're fed up with Barcelona's attitude". "It will seem even cheaper if he plays well in the final".
However, Barca chiefs have agreed to let the Uruguayan forward leave when the transfer window opens, as they are confident of landing the Frenchman from Atletico Madrid according to Catalunya Radio.
He finished off by declaring "enough is enough".
Griezmann has enjoyed another fine season for Atletico, and after strong rumours he would leave the club last summer, the Blaugrana have been tipped to make a move for him at the end of this season. "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".
A report by Cadena Cope radio station, had previously stated that: "Barcelona have told Atletico Madrid they are going to pay Antonie Griezmann's get-out clause. The players know those 90 minutes can define the season".
But the President had denied meeting Griezmann for any talks.
"I can not tell you anything else because I do not know anything else".
Still, defender Filipe Luis - who made his return from a fractured fibula in Sunday's 2-0 loss to Espanyol - hopes the squad's past experiences of playing in big games can work in their favour against Marseille.
