Lucas Hernandez is believed to be on his way to Bayern Munich, but Peton has warned the Frenchman that he may regret leaving.
The former player spoke of how those who depart usually want to come back to Los Rojiblancos, even if he didn't explicitly mention the defender.
"This is a warning for those thinking of going off and exploring," he said.
"Those who go always want to return.
"There is nothing like being at and playing for Atletico Madrid.
"Don't let them trick you, there's nothing like it."
