Alex Song was a notoriously divisive figure during his time at Arsenal and he is unlikely to have gone up in the estimation of Gooners after footage emerged of him celebrating Barcelona's victory at the Emirates Stadium with Dani Alves on Tuesday.

The West Ham midfielder and part-time fashionista moved from north London to Barcelona in the summer of 2012 and went from one of the linchpins of Arsenal’s midfield to a serial benchwarmer in Catalunia.
