It is almost impossible to watch a football match nowadays and not have some sort of opinion about the referee at the end of the match. In recent years, especially after last years World Cup, the referee's have become one of the biggest problems that FIFA chooses not to acknowledge (granted, there are many problems that FIFA chooses not to acknowledge).
While no one is perfect, there have been several high profile mistakes by referee's that have come in big matches. While some of these decisions don't have much effect on the game, some of them have swung tournament outcomes and league title races.
Referee mistakes come in all shapes and sizes, sometimes it's an egregious sending off, sometimes it's an unexplainable whistle (often times the ref won't even explain it!), and sometimes it's just a call that the referee does not make.
This is in no way a definitive list of the worst 10 mistakes of all time. After all, I am very young and can not remember every terrible decision that a referee has made (and there are plenty of them). I tried to pick the ones that have mattered the most to me, and I will admit, I could be a tad bit biased when it comes to some of these.
When compiling this list I tried to look at the magnitude of each decision. Some of them swung World Cup games or title races, others effected the outcome of games, while sometimes, the calls were overcome and in the end they did not matter, but they were terrible calls nonetheless.
Here are the Top 10 worst refereeing decisions in (mostly recent) football history.
