Phil Brown has told EchoSport that he rejected an approach to be Sam Allardyce's assistant manager at Sunderland.
Rumours had suggested that Allardyce would try and appoint the Southend United boss as his number two, and it appears that those reports were correct.
However, Brown was not interested in a move to the Stadium of Light, as he feels that he still has plenty of work to do with the Shrimpers.
“The opportunity was put to me to go to Sunderland but, after talking with the chairman here, I’ve decided to stay at Southend,” he said.
“It was something I did think about for a couple of days and I was considering what would be best for me to do.
“But I still have ambitions I want to achieve at Southend and I also want to try and get to 1,000 games as a manager as well.
“That’s something I’ve always wanted to do and I’m not going to do it if I go and become an assistant somewhere.”
Sunderland are still looking for an assistant manager, with the Sunderland Echo suggesting that Blackpool boss Neil McDonald is a potential candidate.
The Black Cats have their first fixture under the guidance of Allardyce at the weekend against West Bromwich Albion, and it is increasingly unlikely that the new assistant will be in place by then.
Brown, meanwhile, will be focused on ensuring that Southend can continue their impressive form in League One, following their promotion last season.
The Essex-based outfit are currently in seventh place in the third-tier, and they face a match against Barnsley on Saturday.
