It could be on basketball, boxing or horse racing, or any kind of sport, after being in a particular sport for many years can you see or tell if a fight or event is fixed, there are upsets but in the back of our mind, there's a possibility that the match or game is fixed.
In the field of sport, I have seen many fights because there are actions such as basketball that lead to personal or physical pain while playing, and very rarely until the end of the game the result is still good and so on. is not. Even in other sports, the same thing happens as in football.
It's difficult to tell when a game is fixed, in my opinion, because the two teams won't really show it. Instead, they'll try to play their best, but they will intentionally make some silly mistakes that will let you know the game is fixed. On the other hand, some games won't be fixed, but there will still be silly mistakes, making it difficult to be sure. In football, especially, anything can happen, so you can't just assume that because a small club wins the club topping the table, that means the match was fixed. Sometimes the match will be fixed but you won't know it, and you might think the small club is lucky not to have known that the match was fixed.
That's true and correct, its too gard to find in the end that it is fix. But sometimes as I stated in the above it fixed before end of the games something like that.
