Former Arsenal and England defender Sol Campbell has given up on management.
The ex-centre half has worked in the lower leagues since retiring as a player.
"For me, it is about getting opportunities to fail," he told the PA news agency at Web Summit in Lisbon.
"Some of my peers have had jobs and it's not worked out and then they have had opportunities again straight away, they've always had a lifeline.
"That is a nice position to be in. I am not in that position, I would love to be, but those situations are not coming to me. I would love to be involved in football and have chances, but that is not happening.
"You have to look at football in a different way and that is what I am going to start doing and hopefully it will work out and I will be able to help players, just in a different way.
"I love coaching, so I am going to go back into football in a meaningful way. I have had to go away, studied at Harvard. I want to be in football in a meaningful way. It won't be on the sideline.
