How do we do it?

In tennis a player can challenge a call and computer and video replay verify the call. Each player is allowed to challenge three times per set. If the call was incorrect, then the challenge is not deducted from their allotted three chances. If the original was correct, then the player only has two more chances.
In soccer this can be instituted on certain calls where a team feels that it has the capability to change the outcome of the game. In this way it is up to the players' discretion and judgment whether they want to challenge the call or not. This could be very critical on goals that were not counted or on penalty kicks.
