Wolves winger Traore is a former Barcelona player - like Keita - and has spoken of being open to joining Real.
Keita believes Traore should be unconcerned if the option arouse.
"If Madrid want to sign him, I'd go running with those legs he has," said Keita.
Keita also believes Barca defender Gerard Pique is planning to challenge for the club presidency in the future.
"If Pique is the president, I'd return," he told AS.
Asked if that meant that Pique was considering going for the rule he said: "Yes, that's why I said it."
