Former Republic of Ireland boss Martin O'Neill insists he is not too told to be relevant and is ready to return to management.
The 66-year-old was sacked a month ago after relegation from Nations League B but the former Celtic, Leicester, Aston Villa and Sunderland manager is already targeting a comeback.
"I genuinely think that you always have to have the mindset that you have a point to prove," he told the Daily Telegraph.
"Until the last day of your existence, you have a point to prove. That has always been the case with me, right from when I started out as a player.
"I still possess that strong self-belief, I will always back myself. I will back myself in whatever job I take next.
"Maybe there is a perception now that am I not only too old, but that I'm on the outside looking in.
"There is an age element to it, there is a feeling that people believe you have closed your mind to things and it could not be further from the truth. My mind remains open.
"I feel young, I'm ready and I've been involved with young people, with players in my managerial career for quite some considerable time.
"I don't feel that that age should have anything to do with it. I'm ready to return."
