A recent study has confirmed that Manchester United have been the biggest spenders in world football over the last decade.
In a list assembled by the CIES Football Observatory, the Red Devils sat at the summit of the net spend charts - followed by a number of Premier League sides.
In fact, the study showed that the English top-flight is by far the most lucrative league in terms of transfer spending - having splashed out a total of £19.1billion (€23.02bn) since 2015.
A large portion of that is down to just a handful of sides, with United's total spending of £1.
