Sorry Pal, i admire Klopp in every respect as long as it is legal. A good example is that they have a throw-in coach. We're pretty rubbish at throw ins both offensively and defensively. If you watched the Leicester v Liverpool match the scousers won the ball back every time Leicester had a throw in. Klopp is excellent at the fine details of the game.
However, this doesn't mean they are beyond reproach or suspicion in other areas.
Football agents are unregulated. This is the area of the game where the most money changes hands. If the governing bodies are so lackadaisical with the agent system, what makes you think unethical supplements are so tightly controlled?
