Allardyce took over Sunderland in October 2015 and has guided them to Premier League safety.
The Black Cats secured their top-flight status with a 3-0 victory over Everton at the Stadium of Light on Wednesday evening.
“Congratulations Sunderland and to Sam Allardyce for securing Premier League status,” Brady wrote in her football diary in The Sun (Wednesday, May 11 entry). “Sam has never been relegated as a manager and it’s obvious to see why.
“He did a lot for West Ham and will remain a friend to my club. Spare a thought for Newcastle. What a loss to the Premier League they are.”
Allardyce was in charge of West Ham for four years from the summer of 2011 until the end of the 2014-15 campaign.
The Englishman guided the Hammers from the Championship to the Premier League and then established them as a top-flight club.
As for Newcastle, it is sad that a club as big as them will play in the Championship next season.
The Magpies do have some good players, but they have severely underperformed throughout the season and deserved to get relegated from the Premier League.
