    Bolton midfielder Fabrice Muamba has announced his retirement from football.
Muamba, 24, collapsed and suffered a cardiac arrest on 17 March 
    
during Bolton's FA Cup quarter-final tie with Tottenham Hotspur. 
  
              "While the news is devastating, I have much to be thankful for," Muamba told the club website.
  
              "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."
  
              
Muamba had travelled to Belgium earlier in the week to have minor heart surgery, 
     which was said to have been routine and had no bearing on whether the player would return to action. 
  
    
 
 
    
 "The medical response was extremely swift"
 
But Muamba says he received advice during his time there, prompting his retirement.
  
              "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," said Muamba in a statement.
