It's absolutely no surprise to see Ajax at the very bottom of this list - but the margin by which they are may come as a shock.
The Dutch side's Champions League squad cost them just €95 million (£82m/$107m), with many of their key players costing little to nothing - or, in many cases, nothing at all.
Lasse Schone and Klaas-Jan Huntleaar arrived for free, while Matthijs de Ligt, Donny van de Beek and Noussair Mazraoui, among others, do not even need to be registered in Ajax’s main Champions League squad as they are home-grown players born after January 1 1997 who came through the club’s academy.
Goalkeeper Andre Onana and forward Kasper Dolberg arrived for just a few hundred thousand Euros each, but most remarkable of all is Frenkie de Jong's cost - which was, symbolically, just €1.
It's the likes of Daley Blind (€16m) and Dusan Tadic (€11.4m) who make up most of the squad's total cost, after they were recruited by Marc Overmars and his team in order to add experience to this youthful yet talented crop of players.
On an individual basis, one could regard their signings as deals where Ajax have overpaid. But the bigger picture shows that this history-making side has been constructed for an incredibly small price.
At €95m, Ajax cost more than five times less to put together than Barcelona and Liverpool, six times less than both Manchester clubs and seven times less than PSG. This makes their Champions League journey all the more remarkable.
