We've compiled a new study to calculate the maximum potential cost that clubs will pay out from the biggest deals of 2013.
Forget face value, we delve deep below the skin of the deals to uncover the signing-on fees, what the agents have earned and the foreseeable costs the clubs will pay out over the course of each player's contract.
If you thought 100 million euros for Gareth Bale was excessive, prepare yourselves. These numbers are mind-blowing!
Be sure to check out the video trailer above, and stayed tuned to Goal, where all will be revealed on December 17.
