I don't rate him as highly as you do. What is wrong with that? Do I have to form my opinions based on what you, or other people think. That is called diversity of opinions and we agree to disagree.
Thankfully the manager and the club rate him highly as I do and as many others do, hence why he is at the club and is viewed as an important player.
As I said, anyone can have an opinion, that doesn't mean that every opinion is the reflection of the truth. So as much as you have a right to state your opinion, I equally have the same right to speak about on your opinion.
You have an issue with Mane, that much is clear.
