Alan Pardew has spoken for the first time about his sacking from Southampton.
The former West Ham boss left the League One club in August, just two days after a 4-0 win over Bristol Rovers.
But with the cash-rich Saints demanding promotion, Pardew paid the price for failing to get the side amongst the early season pacesetters.
"Obviously there was a breakdown," Pardew told Goals on Sunday. "You have to say the chairman (Nicola Cortese) lost faith in my management and that's all I can assume because there was no other reason.
"I can't give an example of why because he's not allowed to talk about it and nor am I. He's a new chairman and I always felt vulnerable.
"All you can do is do the job to the best of your ability and I was very proud of the team that we built there and the relationship I had with the players, which was very, very strong."
