tapping up a football player

Here's a more detailed explanation:
Contractual Obligation:
Players are under contract with their respective clubs, which means they are not free to negotiate with other clubs without their current club's consent.
The Act of Tapping Up:
Tapping up involves a club or its representatives contacting a player (or their agent) to try and convince them to move clubs, without informing or getting permission from the player's current club.
Why it's Wrong:
This practice is considered unethical and disruptive to the transfer market because it undermines the established process for player transfers and can lead to instability within a club.
Common Methods:
Tapping up can occur through direct contact with the player, through their agent, or even indirectly through media statements expressing interest in the player.
Enforcement:
While the rule against tapping up is in place, it can be difficult to prove, and clubs often resort to reporting such instances only when they are very public or damaging.
Examples:
Notable instances of alleged tapping up include Liverpool's pursuit of Virgil van Dijk from Southampton and Atletico Madrid's accusations against Barcelona regarding Antoine Griezmann

“Selling" club can refuse to deal with the
tappers, but likely they've been doing tapping
of their own.

Agents like monets, so facilitate transfers.

i was thinking, that with modern day technology(AI)it would not be to hard to track and trace mobile conversations and text messages to catch guilty clubs who do it.

years ago it would be talking to players they knew, nowadays it would be talking to agents, which there is nothing wrong with
