I have never seen Sadio Mane playing the main striker role. And he is not able to score a lot of goals and assists. If Nagelsmann wants to use Mane to score a lot of goals then I'd say it's foolish of him. Nagelsmann should either change his match tactics or look for a new striker. Otherwise, Bayern Munich's performance will not improve.
I 100% agreed, Nagelsmann should use Sadio Mane more effectively by giving him a more comfortable role in the team, if they don't have a main role striker then leave it be because watching Sadio Mane plays he is more versatile in making plays assisting his team with good passes but surely he is not used in receiving them, although he can surely play that role aswell, for me, he is more effective assisting the team, while Robert Lewandowski is good at receiving and make difficult strikes near the goal, Sadio Mane is not like that,
There are two issues I believe have arisen in the team as a result of Mane being the main striker. There is neither a good left winger in the team to support the main striker and neither is he capable of playing the role of the main striker properly.
I believe that this problem can be resolved by the addition of a primary striker to the squad. Afterward, Mane will be able to return to his natural position as a left winger, which is the position he comfortably played. In addition, the performance of the team will be much more solid as a result. But regardless of that, I think Nagelsmann's job is under serious threat due to the results that Bayern Munich is producing at the moment.
