Guud Hiddink will take charge of Chelsea until the end of the season, the club has confirmed.
He replaces Jose Mourinho, who was sacked on Thursday with the club languishing in 16th in the Premier League table.
Hiddink has signed a short-term contract, with the club expected to turn their attentions to more viable long-term options Pep Guardiola and Diego Simeone in the summer.
The 69-year-old has been out of a job since being sacked as Netherlands coach in June, following a disastrous second spell with the Oranje.
He returns to Stamford Bridge for his second stint, having taken charge of the club on an interim basis six years ago.
Roman Abramovich installed Hiddink as manager in February 2009 following the sacking of Luiz Felipe Scolari.
He remained in charge until the end of that season, losing just one Premier League match and lifting the FA Cup during his time with the club.
