Barcelona are tracking Arsenal captain Thomas Vermaelen.

The People says Barcelona are keeping tabs on Arsenal defender Vermaelen as they search for Eric Abidal's eventual successor.

Vermaelen, 27, signed a four-year contract extension in October 2011 and was handed the captaincy by Wenger when Cesc Fabregas left for the Nou Camp.

Barca have since also bought midfielder Alex Song from the Gunners.
