I was bidding on a player (not even a very special player). The bidding kept going on. The price almost doubled. Many tokens drained.

Now all of that I can get somehow. Perhaps I could use some thing pointed out.

The player bidding did not seem to be wealthy at all. Not in team value, not in team quality ans last but not least :
not in budget.

How is a player able to bid way over theyre budget?
As it is possible what happens if he wins?

And why is that so?
