Low in confident mood after relaxed training session

Germany will go into the tournament as defending champions, having beaten Argentina in the final in Brazil in 2014. 

"I have a very good feeling," Low said. "I don't know what will happen with this golden generation after the tournament. 

"It's possible there will be a break-up. But all the players are on fire for the World Cup.

"I don't have to coax new craving or new enthusiasm from the players. The craving and ambition are still there, even among those who became world champions."
