It's Money Night Football this weekend in the Premier League.
See what we did there?
Manchester City will entertain Chelsea at Etihad Stadium in their top-of-the-table clash on Monday. It brings together two of the most expensively assembled teams in English football, with the winner taking a considerable step toward reclaiming the Premier League trophy.
Now that the winter transfer window has closed, it got us thinking: With all the money these two clubs have splashed out since Sheikh Mansour completed his takeover at City in the summer of 2008, who has got the best value?
In total, Chelsea owner Roman Abramovich and Mansour have spent over £1 billion on transfer fees alone, bringing in 88 players in that time (City have signed 49, Chelsea 39).
So, breaking these transfers down into the 30 most expensive, Bleacher Report has ranked the top signings made by both clubs during the Abramovich-Mansour era.
