There's nothing wrong with having an ego, but it's how you put that ego across.
Some of the world's best players and managers have egos because of what they've achieved.
However, there are a few underachievers who think that they're better than they actually are, and that's what some football fans have a problem with.
It's not even players and managers that have egos.
Football officials, such as FIFA President Sepp Blatter (pictured above) have this sense of self importance, despite having achieved nothing.
The list of 15 people that I've compiled includes nine players still plying their trade, one retired genius, three managers, an owner and a football official.
One thing I'll say about this list is that—unlike some others that I usually write—this countdown will be in order. This means I've ranked these men in order of who I believe have the biggest egos.
No doubt some of you will agree, but I know some of you will disagree. That doesn't make my opinion right or wrong, it just makes it different than yours. Please take that into consideration when leaving your comments below.
