"It's a fresh start. I can leave behind what has happened but know that I've learnt from it. I've got the passion back now and am looking forward to getting in shape and putting a few things right," he said in a statement.
"To begin with I contacted a handful of world-class trainers and asked Adam if I could have a chat and perhaps get some advice. So, after a brief chat, I brought up the idea of him possibly training me and we decided to have a meeting. I assumed he wanted to see what kind of frame of mind I was in.
"We did a few sessions together just to see how it would work and he then agreed to train me. I was made up about that because I know Adam is very selective when it comes to choosing fighters to work with. I've got a good feeling about this move and truly believe Adam is the man to bring out my true potential."
