Former Bayern boss Hansi Flick has had an excellent start to life as the Barca manager, sitting top of La Liga with nine wins from 10 following a 5-1 win over Sevilla at the weekend.
Barca also got their Champions League campaign up and running on matchday two, thrashing Young Boys 5-0 on home soil.
Here, Sports Mole rounds up Barcelona's injury and suspension news ahead of the matchday three clash with Bayern.
Ronald Araujo

Andreas Christensen

Type of injury: Achilles
Possible return date: November 6 (vs. Red Star Belgrade)
After two months out with Achilles injury, Christensen remains sidelined for now, but he could return ahead of their matchday four clash with Red Star Belgrade at the start of next month.

Bernal suffered an ACL injury against Rayo Vallecano in the league earlier this season, and the teenage midfielder is set to spend the rest of the campaign out.
Marc-Andre ter Stegen

Barcelona will be without first-choice goalkeeper Ter Stegen for the remainder of the season due to the serious knee injury that he suffered in the 5-1 win over Villarreal last month.
