The player remains critically ill in intensive care following his cardiac arrest on the pitch at Tottenham on Saturday night.
Coyle and chairman Phil Gartside were back at the London Chest Hospital on Monday as the player's fiancee called on fans to pray for the star.
Coyle said Muamba's family had been inundated with messages of support following his collapse.
'The message is the good will, the prayers from everybody, they are so thankful and they want to put that on record - to say "keep up the prayers, thanks for all the support"' he said.
