Sadio Mane's market value dropped by 45 million euros in a season since he joined Bayern Munich. I think this was really a big mistake in his career. We were watching Mane - Salah duo doing amazing things at Liverpool. Mane was one of the most crucial players for the team. He wanted a new adventure but this hasn't been going on well for now.
He was injured and that was his first season with Munich but aside from that he is not that bad though with total of 12 goals with 6 assists for 38 games in total. He could have done better yeah but give him another season and he could prove that he is far better for sure but honestly what would you expect from the market value of a 31 years old player anyway?
