Bolton Wanderers boss Owen Coyle has praised the "incredible" support shown to Fabrice Muamba from around the football world.
Muamba suffered a cardiac arrest during Bolton's FA Cup tie with Tottenham Hotspur last Saturday.
"Every one of my colleagues in the Barclays Premier League has been in touch - the text messages, voicemail has been incredible," Coyle said.
"You always know when one of you has problems, it doesn't have to be a player.
"But somebody who works for you, it's close-knit. If one of them is hurting, they are all hurting."
Muamba remains in intensive care but is making some steady progress.
