Federer's attitude towards Nole was drastically changed compared to 2 years before.
Mainly because Novak has bowed to him a lot these last years...
Said that, my mum and dad, truly objective casual tennis fans, despised old Djokovic and adore the new one. I think that's the pattern with most casual tennis fans. Being the showman he is and how nice he is to everyone, people love him right now. I'm not sure which Nole I prefer.
