I fully agree. My point is though, the tapping-up is done discretely, most often via phone calls to an agent. That is, you cannot really prove it. In this instance, Klopp was guilty of meeting in person with van Dijk, and Southampton caught Liverpool out. Following the public apology and withdrawal of interest, I am genuinely curious as to how Liverpool can now be allowed to return for the player without punishment from the Premier League. As you say, Liverpool's crime is less to do with the act itself, given how endemic it is within the game, and more to do with their failure to act discretely. Nevertheless, they have been caught red-handed, and being allowed to still sign van Dijk means the act goes unpunished.
Everyone is guilty of it, Liverpool were just incompetent enough to get caught in the process. It seems odd that it can go unpunished. I'm not suggesting a transfer ban, but at the least I would have expected any further pursuit of the deal to be verboten. It's not as if van Dijk is the only CB Liverpool could possibly sign, they should just have to accept their mistake and move on to someone else. And no, I do not want nor have any hope that City will move for van Dijk.
