Following his most recent subpar performance in a loss at Bayern Leverkusen, Sadio Mane's form and health are apparently becoming a concern for Bayern Munich.
The forward, who just completed a high-profile £35.1 million transfer from Liverpool, was hailed as a star signing at the Allianz Arena in the summer.
The Senegal star has struggled to regain the form that made him such a feared opponent as a member of Liverpool's trinity of offensive studs, which also includes Mohamed Salah and Roberto Firmino, despite scoring on his debut.
The 30-year-old has been largely off the pace since returning from the World Cup injured, according to German publication Sport 1. The German team is now reportedly growing concerned with the player.
According to the source, he appears unfit and consistently loses one-on-one fights, which has been seen multiple times during training.
Due to a lower leg injury, Mane was ruled out of the World Cup on the eve of the event. He underwent surgery and was sidelined for three months, missing Bayern's first seven matches in Qatar.
However, he has only contributed one assist since, and last weekend, after putting on a terrible performance, he was replaced at halftime in Bayer Leverkusen's 2-1 loss.
There are worries that the injury will have long-term effects because he is past his prime and hasn't played with much of his former explosiveness and speed lately.
Nonetheless, despite modest figures of 11 goals and 5 assists through 28 appearances for the German team, Mane has battled for much of the season.
The offensive player must now meet slightly different tactical requirements than he was previously accustomed to under Reds manager Jurgen Klopp.
Under the German, he would play as a winger with a supporting full-back, but Nagelsmann's style places him in a more central position because Alphonso Davies mostly performs the role of the winger.
His most recent strike for the team came against Mainz in October, when he also picked up two assists.
