Bundesliga club Borussia Dortmund will continue to be without midfielder Mario Götze for the time being. The 24-year-old World Cup winner has continually suffered with muscular problems in the last few months, prompting a comprehensive internal investigation into the possible causes.

Those investigations revealed the player has metabolic disturbances, rendering it absolutely necessary to withdraw him from team training for the time being. "I'm currently undergoing treatment and will do everything in my power to be back in training and helping my team to achieve our common goals as soon as possible," Götze said.

"We're happy to have now uncovered the reasons for Mario's difficulties and are convinced that his extraordinary abilities will give us additional quality once he has completely recovered from this," emphasised Borussia Dortmund's Sporting Director Michael Zorc, who continued: "Mario has the full backing and maximum support of everyone at BVB during his recovery!"
