The Dutch striker said: "It's really important to win things. Every day you are working, working, working and that's what you're doing it for.
"Of course, we have lots of respect from people. But I want respect around the world, so that people say: 'They have this fantastic football that I'm really envious of and they have the trophy in their hands at the end'.
"I don't think it's enough just to win trophies with ugly football - and I'm not saying Chelsea are playing ugly football.
"But when a team are really playing a negative way and winning something, I don't really like that. But I don't like it as well that we're playing so fantastic and not winning trophies."
