This guy's nickname is 'cutienelli'? The guy is shit, he doesn't have enough recognition to have a nickname, he's an old man and has barely won a match.
Firstly, yes Chiudi and Cutie sound quite similar. If you don't know how to pronounce his name, don't judge. Secondly, Marco actually has quite a large fanbase and one that has been growing rapidly. Thirdly, for someone with the injury problems that he has suffered from, he has shown a lot of resilience and actual love for the game. Seeing as you are a Safin fan, this is something I am sure you are not much acquainted with.
