Pep Guardiola fears the bust-up between Sadio Mane and Leroy Sane will galvanise Bayern Munich as they try and come back against Manchester City in their Champions League quarter-final.
City are in a dominant position in the tie after winning last week's first leg at the Etihad Stadium 3-0, courtesy of goals by Rodri, Bernardo Silva and Erling Haaland.
In the dressing room after that defeat, Mane struck Sane and left him with a bloodied lip as a disagreement that started on the pitch escalated into violence.
The former Liverpool forward was suspended for just one game - Saturday's 1-1 Bundesliga draw with Hoffenheim - and will be available for Wednesday's second leg at the Allianz Arena.
