Bayern Munich forward Serge Gnabry is a doubt for next month's Champions League clash with Arsenal after suffering a knock in the Bundesliga win over RB Leipzig. Gnabry was substituted in the latter stages of the 1-0 victory at the Allianz Arena on Saturday with a thigh problem. The Athletic understands the Germany international will be assessed by Bayern's medical staff in the coming days to determine the extent of the injury. Gnabry has been in fine form for Bayern this season, scoring 10 goals in all competitions. His absence would be a blow to Bayern, who are looking to win their sixth Champions League title. Arsenal will travel to Munich for the first leg of their last-16 tie on February 23, with the second leg taking place at the Emirates Stadium on March 16.
