Germany midfielder Leon Goretzka believes any lingering issues are behind him as Joachim Low's men prepare for their World Cup defence.
Goretzka will join Bayern Munich from Schalke for next season after his dominant midfield performances established him one of the Bundesliga's rising stars.
The 23-year-old suffered a stop-start spell in the middle of the 2017-18 campaign, but has no worries over his body coping with the demands in Russia.
"I feel like I'm in good shape," he said at Germany's pre-tournament training base in Eppan, northern Italy.
"It's been intense over the first few days at the training camp, but I'm at a good level and I'm ready for the upcoming challenges.
