Pep Guardiola's Manchester City have become the first side in football history to invest more than €1 billion to assemble their squad, while Manchester United are also among the four most expensive squads in the game.
Click through the gallery above to see the 10 most expensive squads in football right now, and how much they cost to assemble, according to CIES.
Although the saying is "money can't buy success", the Citizens have spent a lot in their quest for silverware.
In fact, no team in football history cost as much as Guardiola's side, the International Centre for Sports Studies (CIES) pointed out in their latest report.
City spent another €168 million (R2.7 billion) during the most recent transfer window, with their biggest acquisitions being Rodri, who joined for €70 million (R1.1 billion) from Atletico Madrid, and Joao Cancelo, who City spent €65 million (R1 billion) on in a swap deal involving Danilo, who joined Juventus for a fee for €35 million (R568 million).
As a consequence, the overall expenditure for the Premier league champions' current squad has now surpassed the €1.01 billion (R16.4 billion) barrier.
Guardiola's side became the first in history to reach this milestone, with Paris Saint-Germain and Real Madrid completing the podium.
PSG spent €913 million (R14.8 billion) on their current squad, while Los Blancos invested €902 million (R14.6 billion) in their first-team stars.
Manchester United follow in fourth place after investing €751 million (R12.2 billion) in their squad – more than the likes of Juventus (€719 million, R11.6 billion), FC Barcelona (€697 million, R11.3 billion)) and Uefa Champions League winners Liverpool (€639 million, R10.3 billion).
Bundesliga champions Bayern Munich are, somewhat surprisingly, only in 15th position after spending less than half of what United have on their squad. Bayern's €352 million (R5.7 billion) outlay is even less than what Everton (€486 million, R7.9 billion) have spent on their selection.
