News of Guus Hiddink's appointment as Chelsea caretaker coach was revealed to the world by none other than Football Federation Australia.

In another installment in the governing body's annus horribilis, a tweet was sent and story posted on their website announcing the former Socceroos coach's new job with the English Premier League giants.

Chelsea sacked coach Jose Mourinho on Thursday and speculation quickly grew that club owner Roman Abramovich was going to employ Hiddink at the club he led to FA Cup triumph in 2009.

No official word had been given from Stamford Bridge, but FFA tweeted: "Our former boss has taken charge at @ChelseaFC … Good luck, Guus! #GoSocceroos".
