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 made a mistake but not a mistake for making good decision on moving from Liverpool to Bayern, he made his choices and select Bayern Munich because the pay was good, the mistake I think he made was punching a fellow player which Bayern see as a lack of discipline and they decide to humble him but I think this is unacceptable and not friendly to drop someone career in the name of punishment, he apologized to the player he punched and was also suspended for a match, the punishment is enough to correct his mistake next time.
Tuchel also didn't give him many chances in the matches he managed Bayern Munich. Mane is also not very satisfied with his situation at the team now and he is an unwanted man on one hand.
I wonder how this will end for Mane. I don't feel like he will find a European team anymore. His wage is very high now.
Tuchel used him and allowed Mane to played, the only time he was not allowed to play was during that his punishment from the club and that was towards ending of the season that was why he didn't show up most of the time but if the club wish to sell him, he don't deserve this humiliation to the point of selling him less than what they bought, Mane is more than a regular player.
