Bayern Munich star Sadio Mane has come under the spotlight for his indifferent form this season.
The Bavarians were hoping they were getting a top forward in the prime of his career.
While Mane was outstanding for Liverpool, he has found it tough to adjust to Bayern and the Bundesliga.
A Sport1 report suggests that Bayern coaches are not impressed with Mane at present.
They believe he has lost some of his speed and explosiveness in the final third.
The forward will be hoping he can show his best qualities as the season nears its conclusion.
