According to Yahoo/Eurosport anyway!
http://uk.eurosport.yahoo.com/07012011/58/premier-league-great-players-rubbish-managers.htmlCheer up Roy Keane, you are in good company - scores of world-class players have failed to make the grade in management and your departure from Ipswich puts you in good company.
Bryan Robson - The first of Fergie's Manchester United 'disciples' to establish himself in management, Captain Marvel set an unhappy precedent for the likes of Keane and Paul Ince. Lasted seven mediocre years at Middlesbrough, the most notable of which saw Boro reach two cup finals and go down. Subsequently failed at Bradford, West Brom and Sheffield United.
Ruud Gullit - Skippered the Dutch to their only major tournament success in 1988 but proved too intelligent to be much good at management. Became the first foreign boss to win the FA Cup while at Chelsea but then fell out with the board. Fell out with Alan Shearer at Newcastle, and recently fell out with the whole LA Galaxy squad during a nine-month stint.
Glenn Hoddle - Why it is a bad idea for national teams to take a flier on unproven managers. Hoddle's player-manager spells at Swindon and Chelsea offered little indication of the faith-healing madness he would bring to the England job. Insisted not only on taking part in training but showboating throughout and repeatedly nutmegging a bemused Martin Keown.
Ossie Ardiles - At least he had the guts to impose his own tactical blueprint at Tottenham. Pioneered the novel 5-0-5 formation at the start of the 1994/95 season, employing an attacking quintet of Juergen Klinsmann, Teddy Sheringham, Ilie Dumitrescu, Darren Anderton and Nicky Barmby. Tragically, it failed and Ardiles was out of a job by October.
Alan Ball - If a flat cap and disarming honesty were enough to be a top manager, 1966 World Cup-winner Ball would have been a dugout legend - but Alex Ferguson and Jose Mourinho prove that being a lovely man is not a pre-requisite for success. Was nice enough to gain employment at Blackpool, Portsmouth, Stoke City, Exeter City, Southampton, Manchester City and Portsmouth.
Bobby Charlton - Another England hero from 1966, Charlton's maturity, leadership and track record seemed tailor-made for management. Took Nobby Stiles with him to Preston North End where he became player-manager. It did not go well, and he was off at the end of the season.
John Barnes - 'Super Caley Go Ballistic Celtic Are Atrocious' is pretty much all that needs to be said about Barnes's disastrous tenure at Parkhead.
And two greats who succeeded:
Franz Beckenbauer - Der Kaiser won the 1990 World Cup with West Germany, then proceeded to manage in brief, successful bursts. Won the French title during a single season at Marseille, then snaffled a Bundesliga and a UEFA Cup in spells of six and two months at Bayern Munich in 1994 and 1996.
Johan Cruyff - Introduced a 3-1-2-3-1 tactical system (seriously) at Ajax, which the club used to win the Champions League some years after Cruyff's departure. Then created Barcelona's Dream Team, winning the 1992 European Cup and signing legendary players such as Romario, Hristo Stoichkov, Michael Laudrup and Ronald Koeman.
