The Cameroon midfielder was a regular at Arsenal under Wenger, playing 204 times before his £15million transfer to the Catalans in August last year.
Since then, the big money move to Barca has not paid off for Song as he has failed to hold down a regular first team place even when the current La Liga leaders have been depleted by injuries.
And as a result, it was reported recently that the midfielder was unhappy in Spain and was pining for a move back to north London with the Gunners happy to assist.
Wenger has moved quickly to dispel the rumours and has also encouraged Song to stick it out at Camp Nou and prove his doubters wrong.
"There is no buy-back [clause] in his contract," Wenger said.
"I heard that he wants to give it a go for another season, which you can understand because it's the first season [with Barcelona].
"I think he's a quality player and sometimes the players have to persist when it doesn't go well and not change their mind too soon.
"My personal advice for him would be to give it another go and after two seasons he can still make a decision."
Song signed a five-year deal with Barcelona.
