6) Manchester City – Net Spend: £-560.66m

Etihad

The Citizens have spent roughly £845m on players over the last decade and they have recouped only around £285m of that. In some ways, it is understandable, as they had a lot of catching up to do compared to their rivals.

However, there is no doubt that the very heavy investment from Sheikh Mansour has been the keen reason why City have been so successful in English football over recent seasons.
