Those saying Arsenal are strengthening... well no doubt Cazorla and Sahin would be fantastic signings (not sold on either Podolski or Giroud though) but Barcelona are apparently moving FAST to sign Alex Song (talks underway according to Spanish media and Busquets already talking him up in vintage Barca destabilising fashion) which coupled with van Persie's exit would be the typical Gunner pattern of signing good players but losing good players too so there is no real progress.
