Germany coach Joachim Low has claimed that Andre Schurrle has developed into a better player since joining Chelsea.
The forward scored a hat-trick on Tuesday night as the Germans came from behind to beat Sweden 5-3 in their final World Cup qualifier.
Low believes that Schurrle's £18m move from Bayer Leverkusen to Stamford Bridge over the summer has given the 22-year-old's career a boost.
"I told him recently that last year I wasn't very happy with his development," he told the German Football Association's official website. "But now, in some games with us and in England, he has shown again what he can do.
"He is dynamic, works back well and has a strong finish. His physical strength was also always an issue, but he has worked well. If he continues to play like that, the World Cup will certainly not pass him by."
Germany had already secured their place at next year's World Cup before Tuesday's match in Solna.
