#10. Alex Song – Arsenal to Barcelona
Barcelona have had some curious transfers over the years, none more so than buying Zlatan Ibrahimovic for 40 million euros and Samuel Eto’o, but the Alex Song deal is up there with the worst. While Ibrahimovic quickly got his career back on track, Alex Song hasn’t. He left Arsenal and it has been downhill for him since, and he must be regretting ever leaving the Gunners. After two loan spells at West Ham United he has now moved to Rubin Kazan in the Russian league. At the age of 28, he should be in the prime of his career but has now found himself trying to resurrect his career. Whether he’ll be able to fulfil his talents will remain to be seen.
