World Cup captain Evra and midfielder Ribery were banned for five and three matches respectively for their role in last year's fiasco where France players went on strike to support Nicolas Anelka, who had insulted then coach Raymond Domenech.
Coach Laurent Blanc decided to turn the page when he named his squad to face Luxembourg and Croatia in a friendly four days later by recalling the two 'enfants terribles'.
"They had a certain status in the France team because of their experience. They need humility to return to the group with the same status as everyone else. [If not] I will be uncompromising and will not hesitate to take radical action," said Blanc, who had overlooked Evra for last month's friendly win over Brazil despite the left back's ban ending.
"I have been very clear with him. State of mind will also be a criteria for selection. He must be irreproachable like the others," Blanc said of Ribery.
Evra could start Friday's game as usual left-back Eric Abidal has been ruled out following surgery on a liver tumour, while Ribery will be battling it out for a place on the flanks.
Blanc said he would make himself available to Evra and Ribery should they want to discuss "the new way of life within the squad".
Playmaker Yoann Gourcuff, who reports said had a difficult relationship with Ribery at the World Cup, did not comment on the Bayern Munich player's return but others did.
"They earned it (their place in the squad)," said Diarra.
Right back Bacary Sagna added: "They are human beings like everyone else. They behave like everybody else."
"For the sake of the France team they will have to settle this," he said.
"We're not living in a perfect world. If people do not get along well or do not spend their holidays together, I do not mind," said Blanc.
"But we have to aim at the same target: Euro 2012."
