Sunderland and Peterborough United will play in League One next season.
Peterborough United chairman Darragh MacAnthony has stated on social networking site Twitter that Sunderland are the biggest club in League One.
Sunderland will play in League One next season after getting relegated from the Championship at the end of the 2017-18 campaign.
The Black Cats were playing in the Premier League just a couple of years ago, but two successive relegations have seen them slip into the third tier of English football.

Sunderland will be aiming to bounce straight back to the Championship and will be favourites to win the League One title next season.
Jack Ross’s side will not find it easy, though, as League One is hugely competitive and teams in the division will be determined to win against the Black Cats, especially at the Stadium of Light.
Peterborough chairman MacAnthony has stated on Twitter that Sunderland are the biggest club in League One.
MacAnthony has also praised the Black Cats for their ticket sales so far this summer for the upcoming 2018-19 campaign.
