Stiliyan Petrov says knowing he is ready for new challenges will make it easier to move on from football:
"Since being diagnosed with acute leukaemia in March 2012, I have come to understand and appreciate the way in which this disease impacts the lives of so many people.
I can help and I want to help and, in setting up a foundation to help address the issues involved when people are diagnosed with this illness, I hope to make a difference.
This will be my new challenge, one I will face with all the enthusiasm, energy and drive with which I have faced every single challenge."
