No clubs in Europe have mobilised themselves with cash quite like Paris Saint-Germain and Manchester City.
Hundreds of millions have been spent to build super teams capable of going all the way in the Champions League and now they meet in the last four.
For PSG, owned by the state of Qatar, their resources are plentiful so long as oil continues to sell and there is no sign of money drying up.
They made it all the way to last season's final, only to trip up on the big stage in defeat to Bayern Munich.
