Fabrice Muamba shows off signed copy of Sir Alex Ferguson's autobiography

Retired footballer Fabrice Muamba managed to get a personalised signed copy of Sir Alex Ferguson's new autobiography from the former Manchester United manager.

The 25-year-old posted a photograph of what appears to be a chance encounter with the Scotsman on a train.

The image, which shows Ferguson's message to the ex-midfielder, is accompanied by Muamba's caption: "The best manager in the history of the premier league Sir Alex Ferguson #football #MontBlanc #MUFC."

Muamba was forced to retire from the game last year after suffering a cardiac arrest while playing for Bolton Wanderers against Tottenham Hotspur in an FA Cup match.
