Recalling the incident at White Hart Lane, Muamba said: "On the day, I was fine. There was no heart problem, no irregular heartbeat - there was nothing like that at all. I was in the right condition and I was looking forward to playing the game.

England Under-21 (2007-11):
"Just before the incident, I felt kind of dizzy and couldn't concentrate. My mind went into a different mode and, all of a sudden, I lost control. My heart just stopped and I fell down.
"I wasn't aware of anything at all. It wasn't until I woke up on the Monday or Tuesday that I understood what was going on. I was very shocked because I wasn't expecting to be in hospital."
"I couldn't believe that could happen to me, but then when it happened to Morosini in Italy, that's when I realised how big an issue it was," added Muamba.
"He didn't survive and I survived. I just have to be grateful for the life that I've got now."
Despite his career ending prematurely, Muamba is able to reflect on his achievements in the game, including representing England at various youth levels, winning promotion to the Premier League with Birmingham City in 2007 and playing more than 150 times in the top flight.

"I've lived most people's dream by playing football," continued the former Arsenal youngster.
"I've played in the Premier League and the Championship. I've played for the national team from Under-16 to Under-21, I played at the Under-21 Championship twice and I played in the FA Cup semi-final.
"I'm grateful for it all. I can hold my hand up and say I tried my best."
