Manchester United striker Wayne Rooney says that Sir Alex Ferguson was right to substitute him against Swansea.
Bayern are top of the Bundesliga and breezed through their Champions League group, but Sammer says the Bavarians must pick up silverware both domestically and on the continent.
And he warned, ahead of a crucial opening few months in 2013, that the exit door was there for anyone who does not match their ambitions.
"The claim is (that) we want to be the best in Germany and in Europe. Anyone who does not meet these requirements is no player for Bayern Munich," he told Kicker.
"We must ensure that titles come to us."

They are nine points clear at the top of the Bundesliga as Germany enjoys a winter break from football.
They also have a DFB-Pokal quarter-final against Borussia Dortmund and a Champions League last 16 clash with Arsenal to prepare for early in the new year.
