Germany head coach Joachim Low has revealed that his side's preparations for the World Cup in Brazil next month are going well, but said that both Manuel Neuer and Philipp Lahm will miss Sunday's friendly against Cameroon.

Low said that his squad have come together well in their time so far and have improved tactically and physically in their training sessions over the last week-and-a-half.

"We have worked on a lot of things and I believe we have made a lot of progress, both tactically and physically," he told Bundesliga Live. "Everyone has been very focused during training and the players are all getting along very well, it's a good atmosphere.

"Philipp Lahm and Manuel Neuer won't play against Cameroon on Sunday. Roman Weidenfeller will start in goal. There is still two weeks until the World Cup starts, by which time Lahm and Neuer will be in form."

Germany are in Group G alongside Portugal, Ghana and the USA.
