Seriously, this is not the performance I was expecting from Mane in Bayern much this season, but if I were to say it was injury that killed his performance in Bayern much this season, because when Mane was in Liverpool, he hardly carry long-term injury like the one he has this season in Bayern. But seriously, I still have hope in Mane that he will still do well in Bayern Munich if he does not leave. As for Liverpool's poor performances this season, I don't think it was only because of the mane that left the club, but I may just say Liverpool players were just weak this season. In short, it is not always every season that strong teams are always in form despite of them not seeing any of their first eleven.
Sadio Mané has spent most of the season sidelined with injury problems since joining Bayan Munich. Because of that Bayan Munich did not get any good service from him which led to the purpose of bringing him into the team and Bayan Munich did very poorly this season.
On the other hand, Liverpool's performance this season was messy. Liverpool may have forgotten this season that they are one of the biggest teams in the English Premier League. Because Liverpool's performance was not very good. Sadio Mané's absence may be one of the reasons for Liverpool's poor performance.
