Nottingham Forest have announced the appointment of Martin O'Neill as their new manager.
The 66-year-old is a former Forest player who won two European Cups with the club.
Here, Press Association Sport remembers five other former heroes as players who went on to manage their clubs.
Sir Kenny Dalglish
'King Kenny', one of Liverpool's most celebrated players, became player-manager in 1985 and promptly led the Reds to the Double. The Scot returned to the hot seat in 2011 and won the League Cup while reaching the FA Cup final, but Liverpool could only finish eighth in the Premier League and Dalglish left in May 2012.
Kevin Keegan
Keegan only spent two seasons as a player at Newcastle, but gained hero status after scoring 48 goals and helping them to promotion. His popularity was enhanced when returned as manager in 1992, saving them from relegation to the third tier and then achieving promotion the following season and putting together the swashbuckling side which so nearly won the title in 1996. Keegan returned again in 2008, but resigned after eight months.
Alan Shearer
Shearer, Newcastle's record goalscorer, answered the club's plea to save them from the drop in 2009 when he was parachuted in with eight games remaining and the team two points from safety. But they won just one of those matches, climbing briefly out of the bottom three after beating Middlesbrough, and were eventually relegated by a point.
Glenn Hoddle
Tottenham's Hoddle was widely regarded as one of the most gifted midfielders of his generation. A forward-thinking coach, Hoddle had managed Swindon, Chelsea, Southampton and England before finally pitching up at White Hart Lane in 2001. But Spurs could only finish ninth and 10th, losing a League Cup final to Blackburn, before Hoddle moved on in September 2003.
Ole Gunnar Solskjaer
Appointed to replace Jose Mourinho at Manchester United until the end of the season, Norwegian Solskjaer is making a decent fist of his audition for the permanent role, with six wins from his first six games. A hugely popular player at Old Trafford, Solskjaer will always be remembered for his stoppage-time winner against Bayern Munich in the 1999 Champions League final.
