Dealing with negative/toxic person in the team

I have this most toxic and most talented developer in my team. He doesn’t know what scrum master does.
He has multiple verbal attacks in the dailies and retros on me, Which I ignored. He thinks that because I don’t do anything I should not be there. We can't lose him. He brain washes the rest of the team members against me and mocks everything I do, mostly with sarcastic comments and arguments.  
Should I sit down/talk with him and ask him how can we resolve it?
Can I talk about this in retro among everyone ? Or in on a one to one base meet up?
