Arsenal have signed Bastia defender Alexandre Song on a one-year loan deal.

The two clubs have also agreed a fee of £2.75m if Arsenal decide to sign him on a permanent basis next summer.

Song, who is the nephew of former Liverpool player Rigobert Song, made 34 appearances last season for the French club.
