The 22-year-old joined Chelsea from Bayer Leverkusen this summer, becoming Jose Mourinho's first signing of his second spell, and is well aware of the Portuguese's warning that players must feature regularly for their clubs to earn a place at next summer's showpiece tournament in South America.
"For every player it's important," Schurrle said. "You have to do a good job for the World Cup. We have big goals for the German national team next year. It's really important.
"We have to see. We have so many matches, so many games to play, so every player is needed and is important for the team and so am I.
"Everything is a big motivation now for me. The World Cup, of course, but here in the team to play, to improve myself."
Schurrle is competing for one of three forward berths behind a central striker where competition is intense.
There is also the potential for Rooney to fill one of the positions, if he signs, although Mourinho would favour the England man as a striker. Schurrle is unfazed.
"In every big club there will always be good competition," he said. "That's what I wanted. I wanted this move, I wanted this step. I have to train hard, I have to work hard and then we will see.
"I want to improve myself, I want to improve all the time and what I really want is to help the team, with my qualities, to be successful."
