Sacked England boss Steve McClaren is already seeking new work.
"There will be another challenge although I don't know where that will be or what that will be, but there will be another challenge because that's me.
"I want to work, I want to contribute and I think I've still got a lot to offer football.
"It's only been two weeks. It seems like a lifetime, it will take me a while, take the fans a while, take the country a while to obviously get over the disappointment of not qualifying.
"That is something that will live with me for the rest of my life, it's a huge disappointment.
"In the new year, I'm going to start getting back into some work, and involvement in football at some stage because I still believe I'm a football person, I'm a coach, I'm a manager.
"I've worked all my life in football and I want that to continue."
