Ah, Paul Pogba - that talented yet ultimately frustrating conundrum that even the most illustrious managers in world football have not quite managed to solve.
Rewind ten years and he was arguably one of the most exciting young footballers in the entirety of the game...but no longer. The Frenchman has now reached his 30th birthday - the peak for most professionals - but now looks likely to round off a career of unfulfilled promise with a few rare highs.
Pogba, a product of the famed Le Havre academy, has always been a figure that has courted debate. Two spells at Manchester United saw Pogba display his huge promise and ability but those times were ultimately punctured by disagreements with managers Sir Alex Ferguson and Jose Mourinho, as well as long spells on the treatment table.
