Bolton's Muamba invited to Royal Box for FA Cup final
Muamba suffered his cardiac arrest in the quarterfinal against Tottenham.
The England Under 21 ace is now at home recovering with his family in Cheshire after being released from the London Chest Hospital last week.
Muamba was back in London on Thursday for check-ups. While he says he finds it difficult to walk any distance without feeling tired, he says he will not rule out playing professional football again.
