Sam Allardyce says he had to take the managerial vacancy at Crystal Palace last season to “overcome the depression” of losing the England job.
Allardyce was appointed England manager in July 2016, replacing the outgoing Roy Hodgson after failure at Euro 2016.
He lasted just one match in the job however, having to leave after being incriminated in an undercover newspaper investigation.
The 62-year-old was back in the game within three months however, being appointed as Crystal Palace manager, and subsequently guiding them to Premier League safety.
He left in the summer, but remains “very grateful” to the club for helping in his time of need.
“I was in shock for two or three weeks just trying to get my head around what happened,” Allardyce told talkSPORT.
“I was in a daze, I was staring into the abyss.
“And of course the good thing is when you’ve got your partner next to you to help you through these situations then you have to come out of it at the other end.
“You have to get over it and as disappointing and as devastating as it was for me – I am bitterly disappointed that I am not the manager of England – but I have recovered from that.
“I’ve moved on and everybody’s seen that I have moved on by taking a very good position at Crystal Palace.
“I am very grateful to Crystal Palace – hugely, hugely grateful. Crystal Palace was one of the things I felt I had to do to overcome the depression and the disappointment that I had suffered in the short spell I had with England.
“I had to get back to work and I had to get my teeth into another position to get over and move on, move forward, and life is very good at the moment.”
