The Blues have Thomas Tuchel back with them after the German flew out to Abu Dhabi on Friday ahead of the Club World Cup final.
Tuchel missed the semi-final due to testing positive for Covid-19, but after two negative tests he was finally able to join up in a big boost for Chelsea ahead of their clash with Brazilian side Palmeiras.
Romelu Lukaku got the goal against Al Hilal earlier this week to send the Blues through, and keep their hopes alive of securing the only trophy they are yet to win under owner Roman Abramovich.
The Blues lost in the final of their only previous Club World Cup appearance, beaten by another Brazilian outfit, Corinthians, in 2012.
Palmeiras have reached the final of the tournament for the first time, after a comfortable 2-0 win over Al Ahly in the last four.
