The boys are back in town

In the early hours of this morning, Manchester United finally secured the signature of now world transfer record man Paul Pogba. United will pay Italian club Juventus Turin a grand total of 93.2 million British pounds for the French player's services over the next five years - with the option of a one-year extension.

While the huge transfer fee will dominate the headlines, it is also interesting to note that Manchester United had Pogba on their books only four years ago. Back then, he couldn't quite curry enough favour from Manager Sir Alex Ferguson and left under strained circumstances as a free agent - United eventually receiving 800,000 pounds after a tribunal. That makes for a loss of 92.4 million pounds.

Pogba isn't the only player to return to his old stomping ground. Other high profile examples include Mats Hummels' arrival back in Munich - also resulting in a loss of 28.7 million pounds after a seven year hiatus in Dortmund. Looking the other way, world cup winning goal scorer Mario Götze signed on a 22.1 million pound trip back to his first club this summer - the BVB this time appearing to have done better business, chalking up a 9.35 million pound profit.
