Germany national team manager Joachim Low believes his side can benefit from Timo Werner and Kai Havertz taking the next step in their careers at Chelsea.
The duo left the Bundesliga this summer in favour of moves to Stamford Bridge, with Havertz joining from Bayer Leverkusen on Friday in a deal worth £70 million ($91m) including add-ons.
That transfer followed Chelsea's signing of Werner in June, with the striker moving from RB Leipzig in a £47.5 million ($59m) deal.
