His role at Chelsea is still to be determined, with his relationship with Jose Mourinho said to be strained in the past.
However, the powerful striker has spoke about his future, and stated that he needs to be playing in the Champions League from next season.
"I'm still young but I've no time to waste,” he revealed to Het Laatste Nieuws.
“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."
