Fabrice Muamba has confirmed his retirement from football on Bolton Wanderers' website. He said in a statement:
Since suffering my heart attack and being discharged from hospital, I have remained utterly positive in the belief I could one day resume my playing career and play for Bolton Wanderers once again.
As part of my on-going recovery, last week I travelled to Belgium to seek further medical advice from a leading cardiologist. But the news I received was obviously not what I had hoped it would be and it means I am now announcing my retirement from professional football.
Football has been my life since I was a teenage boy and it has given me so many opportunities.
Above all else, I love the game and count myself very lucky to have been able to play at the highest level. While the news is devastating, I have much to be thankful for.
I thank God that I am alive and I pay tribute once again to the members of the medical team who never gave up on me. I would also like to thank everyone who has supported me throughout my career, and the Bolton fans who have been incredible.
I am blessed to have the support of my family and friends at this time.
