Former England boss Steve McClaren believes he can 'prove people wrong' and still be a successful manager.
McClaren has been out of the game since being sacked following England's failure to qualify for Euro 2008 in November.
The 46-year-old is looking for an opportunity to get back into management and has taken encouragement from his England predecessor Sven-Goran Eriksson, who has impressed this season in charge of Manchester City.
McClaren told Setanta Sports: 'It didn't help that we [England] didn't succeed. That is a huge disappointment and it will take a while to settle that down, to get that out of my system as well as everyone else's.
'But I just want to get back into the game.
'I have said it before - I think I am a better manager for those 18 months.
'I have got to make sure I prove people wrong. I take massive heart from what Sven has done and know that I can do the same.
'I have coached and managed and worked on the field for the last 20 years and that is what I want to do. I have just got to wait for the next challenge.'
McClaren admits he is concerned for the future of the English national side due to the quality of coaches and players available.
The Football Association turned to Italian Fabio Capello to succeed McClaren and the number of English players playing in the Premier League is being restricted by foreigners.
McClaren added: 'The biggest thing for me is, we have to look at our game, and not just the players.
'When you look at the Premier League, 38% are English players - that is not enough.
'And only a small percentage of those are playing for the top four, in the Champions League, getting big-game experience.
'International football is a completely different level. It is 10 times the standard of domestic football and the only thing that emulates that is Champions League.
'Not enough of our players are experiencing that.
'So we've got problems at player development and we've also got problems with coaching development because there isn't a viable English candidate to take over.'
