Liverpool FC...
And for something interesting about them... Anfield was originally the home stadium of our rivals, Everton. But they had to move to Goodison Park (from which they've moved this year, although, the Women's team will keep on using it) because of Anfield having high rent and Everton not having much money.
Also, this one is kinda embarrassing, but Liverpool fans caused English clubs to be banned from playing European competitions from 1985 to 1990... LFC fans attacked Juventus fans during the 1985 European Cup final and many people were injured there :-(
