Ok... but 10 pages in, are we any closer to answering the question posed in the thread title?
Because maybe that should take priority before making numerous posts about some completely random baseless claim.
While I haven't exactly looked at their squad's medical records, it has been reported numerous times that when Klopp arrived, suddenly a slew of Liverpool's players were diagnosed with asthma and prescribed medication for it. If I recall, Dortmund also had a wildly unrealistic number of players diagnosed with and medicated for asthma. It's just a trick he uses, and nobody is doing anything about it. There are many different kinds of medication that are banned when used as performance enhancers but allowed if prescribed for a documented condition. It's just that they obviously don't have asthma.
When you don't actually have the condition, the medicine is definitely a performance-enhancing drug. What shouldn't be allowed is falsely diagnosing players with a condition that they don't have in order to permit a performance-enhancing drug, but nobody is investigating and enforcing this. If you can get a doctor to vouch for it, you can take the drug. Simple as that. Same way Messi was allowed to take human growth hormone in his youth because of his growth hormone disorder, which is a banned substance unless it's a prescribed treatment (which, in his case, was legit).
I have no idea what proportion of players at other clubs have asthma. I recall that Paul Scholes was notably asthmatic, and it was reported as unusual that a top player had a respiratory condition. I'm guessing it's not normal for 63% of any club's players to be (supposedly) asthmatic. Are Liverpool cheating? Well, not in the sense of breaking any clear-cut rules. If you're diagnosed with a condition and prescribed medicine for it, you're allowed to take it and play football. False diagnosis is just one of those grey areas. Is it dishonest and unsportsmanlike? Of course. But it is self-evidently allowed.
It's just that when you take medicine for a condition that you don't have, you're at risk of adverse effects. Some theorized that this is what led Klopp's Dortmund team to collapse abruptly, and him to depart. Asthma medicine is meant to bring a person with, say, 80% lung capacity back up near 100%. When used by a person with 100% lung capacity by default, the performances that can be achieved with this medication can have consequences in the long term. One might point out that Liverpool's players aren't really known for their longevity. They have a wildly unusual lack of older players.
