Newcastle and Sunderland are in the Premier League at the moment, but both could find themselves in the Championship next season.
The Magpies and the Black Cats are in serious danger of going down at the end of the season, and it is virtually guaranteed that at least one of them will play in the second tier of English football during the 2016-17 campaign.
Warnock believes that Newcastle and Sunderland playing in the Championship would boost attendance figures at the AESSEAL New York Stadium for Rotherham’s home matches.

Newcastle and Sunderland are two of the biggest clubs in England, and both of them regularly attract almost 50,000 fans to their home matches.
The fans will certainly pack St. James’ Park and the Stadium of Light in the Championship next season, and the two clubs will have a strong away following as well.
The presence of Newcastle and Sunderland in the Championship is not only going to boost attendance figures at the AESSEAL New York Stadium, but it is also going to increase crowd numbers in other grounds in the division and and will encourage more home fans to go to matches.
