Arsenal were knocked out by the Spanish giants in the knockout stages both in 2010 and 2011 and the draw for the last 16 of the Champions League will be staged in Nyon, Switzerland tomorrow.
Song, 25, said: “Of course, I would like to play against Arsenal.
“For me to go back there, where I had seven magnificent years, would be something very special.
“If we draw Arsenal I’d be happy to see the fans again, go back to the club, even though if we go there it will be to get the best result possible.
“Arsenal’s a big club, but I think Barcelona’s a level above, because of the talent of the players there.
