The Arsenal manager is confident that the Cameroon midfielder can be a star in the Blaugrana jersey, but believes he would be best deployed at center back
The midfielder, who played under the stewardship of the French coach for seven seasons, was criticized by sections of the media for his performance in the Catalans' 3-2 Champions League victory over Spartak Moscow last week.
Nevertheless, Wenger maintains Song has the quality to succeed in La Liga, and has issued advice to coach Tito Vilanova about how to best employ the Cameroon international.
"He will succeed at Barca, and something tells me that he will play in central defense," he told BeIn Sports. "No matter who's by his side, he will be good in this role."
Song made almost 200 appearances for the Londoners after his arrival from Bastia in 2005, but the majority of these came in a defensive midfield role.
However, Barcelona has a tendency to deploy its holding players at center back, a tactic used by Pep Guardiola to accommodate Yaya Toure and Javier Mascherano in his plans.
Barca looks to maintain its 100 per centstart to the season at Sevilla on Saturday.
