By Mark Bryans, Press Association West Ham have announced the signing of Barcelona midfielder Alex Song on a season-long loan. The 26-year-old Cameroon international struggled to hold down a regular place at the Nou Camp following a move from Arsenal in 2012 and returns to the Barclays Premier League with the Hammers - who paraded their new addition to fans ahead of the clash with Southampton. Clubs throughout Europe were put on alert when it emerged Song would be allowed to leave Barcelona - with West Ham having won the race to take him to Upton Park on a temporary basis despite reported interest from the likes of Napoli and Galatasaray.
