10. Gabriel Obertan
A Newcastle United first team regular in 2015/16, no less... Earmarked as one of the most promising wingers earlier in his career, Sir Alex Ferguson saw enough to justify a
£3 million transfer on a four year deal. However, the former Bordeaux man would soon prove that the promise he showed was deceiving, as a lack of playing time ensued. Step up Alan Pardew and Newcastle who signed the winger on a
five-year deal in 2011, even though made just 28 appearances in two full seasons at Old Trafford. After a bright start as part of the team that went unbeaten until mid-November in 2011/12 campaign, the Frenchman's form stopped, and he was soon cast aside at St James' Park. However, 2014/15 would see a resurrection that carries on to this day. What a heart-warming tale...
