Not a fan of his but he's entirely correct to point out how unhealthy the relationship is between football and the gambling industry. In my opinion it's completely unethical that people should be bombarded with gambling advertisements when watching televised sporting events. It's entirely up to an individual whether or not they choose to gamble or not, but we have to accept that it is something that people can become addicted to and it can have devastating consequences for both the addict and their family and therefore I'd rather we saw the advertising of it banned. A lot of the adverts we see encourage impulsive gambling and I think that's pretty dangerous.
Even as an addict, there's plenty of things he could have been gambling on outside of football, so im not sure that side of his argument entirely tallies. That said, im not a gambling addict myself so it's impossible for me to understand someone in that position. Gambling on his own team to lose though is definitely something that can't be excused. Even if he wasn't playing in those matches he could be deemed to have had inside information and influence on the squad, there's no way something like that cant go unpunished.
