The imminent re-instalment of Jose Mourinho to Stamford Bridge has prompted many to ask: is it a good idea for managers to return?
Nearly seven years after Chelsea sacked the man who lead them twice to Premier League success, the so-called 'Special One' is coming back to London. It may have been a poorly kept secret, but that hasn't stopped many commentators from wondering whether Mourinho's move is a wise one.
In football, the unwritten rule is that managers should never look back, according to independent.ie; take the example of Kenny Dalglish at Liverpool or Kevin Keegan at Newcastle as two cases in point.
In business, however, there seems to have been a recent trend for companies inviting back ex-leaders in an attempt to improve flagging company performance.
Some of the most high profile examples include Proctor & Gamble, which replaced its CEO with his predecessor and software firm, Infosys, who's share price jumped four per cent when it was announced it was bringing former chief Narayana Murthy out of retirement. He described the news as an "exciting yet somewhat new challenge".
Not to mention the re-employment of Steve Jobs at Apple and Starbucks' founder Harold Schultz after an eight-year absence - both of whom managed to turn their companies' fortunes around, bbc.co.uk writes.
Understandably, some people view 'Boomerang Bosses' as a move that helps restore shareholder and employee confidence. Others, meanwhile, believe it is simply a sign of a poorly-executed succession plan which highlights the difficult state a firm is in. It will be interesting to see whether Mourinho succeeds second time around.
