There are some stadiums in World Football that are like a fortress for their home team.
Regardless of the stature of the host team, though they are generally the best teams in their respective leagues, these stadiums can be tough for any team to play in.
Now, most folks can name a few of these stadiums off the top of their head. La Bombanera, the Westfalenstadion as well as the Ali Sami Yen stadium (now Turk Telekom Arena) and others come to mind.
Those stadiums are known for the atmosphere created by the crowd, which sometimes has a debilitating effect on their opponents. Some of these stadiums are also the home stadiums for national teams but we are focusing on the club teams that call the venue "home."
What we'll do for this list is look at stadiums that are generally considered the most hostile, intimidating venues to play in, and maybe a few others as well, and judge them by their win percentage*—That is the only factor that matters for this list.
That shows just how good these teams are at home. Of course, we know that the atmosphere of a stadium certainly plays a part but, again, for this article, the home team's ability to win there is what matters.
To do this we'll look at at 100 home games, mostly recent ones, for each of these stadiums. In cases where there is more than one tenant—it's usually only two—the tenants combine to make up the 100 games.
Within those 100 games teams have to have a win percentage of 70 percent or more at their stadium. Draws count as half a win.
In no particular order, here are world football's toughest opposing stadiums to play in.
