So, we dont really do cheerleaders in football. But the fans in europe are know for leading the way in chants and songs to support the team.
Liverpool fans singing 'You'll never walk alone' is one of best known.
And chants for home players, or against opposition ones, are often witty and based on well known songs.
As for the socks, players wear shin guards beneath them. Some players like to wear thrm rolled right up, some like them rolled down a bit.
It was really interesting watching them pass the ball, as they would often bypass fellow players that I thought they'd target, in favor of one a litrtle better placed. You're right about the singing, I'd forgotten about that from clips I'd seen online. These were company teams playing against each other, so I'll see if my British friend is in any other soccer games.
