Bayern Munich are reportedly growing concerned with the form and fitness of Sadio Mane following his latest poor display in a defeat at Bayern Leverkusen.
The forward was seen as a star arrival at the Allianz Arena in the summer after completing a high profile £35.1million switch from Liverpool.
Yet despite scoring on his debut, the Senegal star has struggled to recreate the form that made him such a feared opponent as part of Liverpool's trio of attacking stars including Mohamed Salah and Roberto Firmino.
German publication Sport 1 are now reporting the German side are growing concerned with the 30-year-old, who has been largely off the pace since returning from the World Cup injured.
