Marseille V Arsenal Champions League Group Stage: Key Battles

Alex Song v Lucho Gonzalez

Although used as an emergency centre-back at times this season, Song’s primary role in the Gunners side is to break up play in front of the back four and release more dynamic team-mates. Argentina international Gonzalez will be the man to catch his attention in Marseille. With an eye for goal and a tendency to support the attackers through the middle, Song will need to starve him of time on the ball to negate the opposition gameplan.
