Former Germany coach Jurgen Klinsmann believes Michael Ballack should end his rift with current national team boss Joachim Löw by issuing an apology.
Ballack and Löw are set to hold talks over the Germany captain's international future following the Chelsea midfielder's remarks that the coach lacked respect for the older players in his squad.
It is uncertain when those talks will take place as Chelsea manager Luiz Felipe Scolari yesterday told Löw to come to their Cobham training ground if he wants to talk to Ballack.
But for that to happen, Klinsmann - who is now in charge of Bayern Munich - feels Ballack must first say sorry for his recent comments.
''The situation is simple: Michael must apologise to the coach and his team-mates for these comments,'' said Klinsmann.
Bayern chairman Karl-Heinz Rummenigge has also told the former Bayern player he should take the first steps to resolve the issue.
He said: ''It is not right to criticise the coach in public and Michael Ballack must admit he has overstepped the line. He has got to apologise to the Germany coach.''
Bayern and Germany midfielder Bastian Schweinsteiger hopes the issue is dealt with soon.
''All I care about is that everything is cleared up by the England game so that we can concentrate on football again,'' he said.
''That is how most of the national team players feel. Germany face England in an international friendly in Berlin on November 19.
