Speaking to Het Laatste Nieuws, he said: "I'm still young but I've no time to waste. The only player who can make a better player of me, is me. I want to be successful, an ambition I share with Vincent Kompany and Eden Hazard.
"I want to be a top player and I also think I can shout that out. I've scored a lot of goals, but I haven't won many titles or cups yet. I want to win something.
"I still have two years on my contract in Chelsea and I know they're tracking my evolution. In the end, it's up to the manager to decide.
"If I become a better player than last season, who'll stop me? It's also time for me to play Champions League, and that's what I want.
"When I turn 21, I'll have been a professional for five years, I need this in my evolution. Cristiano Ronaldo and Wayne Rooney were already in the Champions League when they were 23 or 24. I don't want to play my first games in the Champions League when I'm 23, I want it now. I have to show now that I'm ready."
