Allardyce said: “I thought at the end of last season that maybe enough was enough but that was probably just an emotional reaction to leaving a club [where] I had four very successful years, thinking 'should I carry on, should I do it again?’”
Claiming that his four years at West Ham were successful is maybe an overstatement, having managed to bring them to the top flight and then establishing them in the Premier League.
However, he never achieved any major success, and his best finishes were in mid-table, playing s brand of football that had few fans supporting him.
The Hammers decided not to renew his contract at the end of last season, and Allardyce left so the club could bring in Slaven Bilic, who has started the season well.
It was this decision to let go of Allardyce which caused the 60-year-old to think about ending his career, believing that he had achieved all he could with this ‘enough is enough’ philosophy.
There were no indications that he was looking to force his way back into a job, but when Sunderland came calling following the departure of Dick Advocaat, Allardyce decided to accept the job.
Allardyce’s main task is to keep the Black Cats in the top flight, and it remains to be seen whether his aim is achieved - and his decision to get back into football is rewarded.
