She comes from a TV that is perceived as rich/trashy, something like Serbian version of FOX
However, the best possible PR for Novak is what he's doing on the court.
Who will manage his appointments and fetch the sandwiches is not that important I think
I'm not disagreeing that, at the end of the day, it's him and his action on the court who/which establishes his name, as you said.
But I do care about how competent his PR
manager is for the job, because I think it actually affects his game in a way and part of his bad reputation he got in the past was due to poor management job. With better guidance, he may not have had to deal with such severe criticism for several years & could have avoided some misunderstand or he/she could've preserved Nole from costing so much energy by off-court stuffs. Whether it's stupid or not, he loves to be liked, it's just in his nature. So I feel it does matter for someone like him. Maybe I'm asking too much from a PR
Having said that, I believe he's learned a lot from the experience and won't make the same mistakes again.
For the record, I don't like IMG-like strict and studied management, also don't pay attention that much to how many/lucrative sponsorships Nole gets either. I just wish him to get the right amount of credit for his efforts and achievement without any unjust criticism and to be able to fully focus on his game.
