Germany coach Joachim Low has admitted Bastian Schweinsteiger and Jerome Boateng are both injury doubts ahead of Sunday's World Cup last-16 encounter with England.

Schweinsteiger is struggling with a hamstring problem while Boateng is troubled by a calf strain, both players having suffered the injuries in Germany's final group game against Ghana, website soccernet.com reported.

"There is simply no way I can say at this stage whether one, or both for that matter, will be on the pitch on Sunday," Low said, "Neither of them will train with the team today, that's for sure. It would be major risk, too much of a risk, to include them in training sessions."

"We will take it day by day. Let's wait and see what happens tomorrow. We need players who are 100% fit and not 90%. We need players who can give their all in order to survive - 90% is not sufficient. They have to be fully match fit."

Low revealed both men had already received intensive treatment just to put them in with a chance of playing.

"Hats off and great compliments must be paid to our medical staff," he said. "Straight after the game and until late into the night and yesterday our team worked flat out to deal with Boateng's and Schweinsteiger's muscle problems. We can say there is a major question mark over both players."
