Toni Kroos believes the workload on players who compete internationally is a heavy burden in the modern game.

"I am of the opinion that the burden of playing games is much too high, especially for international players that also play domestically with their clubs," Kroos told Welt am Sonntag.

"During the season, the teams play every third day, that's a huge workload with some long journeys. I think in football we need more time to rest and recover.

"It's no coincidence that in the past two months so many players have been injured, and we're not just talking about strains, but serious problems like muscle tears."
