What makes them big? They've barely ever won anything in their history and have spent about 30% of their history outside the top division. Their only claim to being a big club is doing well in the period directly after the PL was launched and having a big stadium, again I say meh.Saudi Sportswashing Machine aren't a big club? You have no idea what you're on about man.
Forest haven't won anything since the 80s, massive club. Derby since the 70s. Leeds the 80s. All big clubs with storied legacy. It's not uncommon.
I rate successful as the largest determiner in size. The big clubs are the successful ones.
