No idea why the Championship gets labelled as tough and aggressive. It just isn’t, it’s lower quality. PL clubs have young strikers who aren’t equipped to deal with PL defenders so they send them down on loan into the Championship. They don’t all return covered in scars and with cabbage ears and missing teeth, staying in digs with an old pervert. Same with young defenders.
Sexy Marco’s Fulham didn’t romp it by carrying knives to away matches.
The Chamionship isn’t tough to get back out of because they are all hardmen and you play 486 games every week on boggy pitches. It’s hard because the second you go down the majority of your PL quality players leave and you become just another Championship team.
