I don't know, that picture does make it look dangerous in that it could break an ankle if he's standing flat footed so if that's the case then fair play it's a red. This isn't much of an issue, but for me the biggest problem I have with the sport is the way fouls are called these days. You get fouls for contact rather than obstruction. Your hand could brush someone's arm when running next to them and they will dive and be awarded for the contact, even though there is no way in a million years that caused a foul.
I like the quality of football from abroad and how it's improved the Premier League, and I like the improved quality of tackling that has followed it. But I hate the blatant diving that is awarded simply for contact being made in a contact sport. It just creates a safe space for grown men to hit the floor and roll as if someone killed their children, it's not the same level but I've been elbowed in the face by someone twice my size in Saturday league and funnily enough it didn't stop my legs from working. Footballers nowadays get the tiniest of touches and go down, I don't like seeing players get injured but whenever someone takes diving to an extreme I pray to the gods that created Roy Keane that his spirit will take control of someone's body and they get absolutely slaughtered in the tackle.
It was great when Neymar got put out of the world cup in Brazil, karma coming back full swing. Just needs to happen to a lot more players.
But back on topic....I agree, red card
