But it takes a week before it starts selling them. I have had opponents go into BIG debt for a Cup match. Easy enough to do, that only represents like 3 players worth, at my level anyway
They are basically renting the players unless they spend Tokens to bail out. Often when you find one good player there's more you want, so you can place all the bids on before you've spent any $$, get the players, go into the red.
