Why do you think he needs mental help? He’s a millionaire in his early 20s who is clearly enjoying his life, he just doesn’t like playing football anymore.
He’ll decide if he wants to change his attitude, modern football is full of lads like him, it’s nothing to do with mental health.
You may be right.
You may also be wrong.
None of us knows or has an insight into the state of his mental health, so it is distasteful to speculate.
By the way, being wealthy does not preclude anyone from mental health issues.
Mental health is no joke, so pay the topic the respect it deserves. End of story.
