Munich (dpa) - Hansi Flick fades before his exciting premiere as an interim coach past and future at Bayern Munich simply.

"The present is crucial for me," emphasized the 54-year-old before today's match one of the German football record champion after the separation of Niko Kovac (18:55 clock) against Olympiacos Piraeus in the Champions League.

The job for the former assistant of coach Joachim Loew in the first two games as a backup boss is to bring the team back on track. Flick laces home against Piraeus and on Saturday in the Bundesliga against Borussia Dortmund to a package. «We have two difficult games. And we have to get rid of all the grains that are in us », is the demand on his team that knows" that they are responsible ".

STARTING POSITION: The deterioration of form from the intoxicating 7: 2 in early October in London against the Champions League finalists Tottenham Hotspur to disastrous 1: 5 of Bayern at the weekend in the Bundesliga against Eintracht Frankfurt is extreme. Flick should immediately ignite the reverse thrust, even if he had little time to work with the team. A training and many one-on-one discussions with the players are to be effective in the sold-out Munich Arena. It could simply not be the case with the high quality of the squad that only goalkeeper Manuel Neuer and top scorer Robert Lewandowski constantly play on "world-class level". Another central starting point for Flick is better defense work: "The goals we got is not Bayern-like. That's where we have to start. "

CHANGE: Flick will make changes - tactical and personal. He has against the Piraeus League league against Dortmund already in view. "I want to have a team that's already recorded for Saturday's game," he said. Javi Martínez (31) will play in central defense against Olympiakos. Finally, in addition to the long-term injured Niklas Süle and Lucas Hernández against BVB Jérôme Boateng is also missing. Flick also relies on the "identification figure" Thomas Müller (30): "He is one who can carry a team and lead."

GROUP: After the 3-2 win in Piraeus two weeks ago, the Bayern as leaders with a home win against the Greeks prematurely solve the round of 16. "We have to see that we win the game," said Joshua Kimmich. The international sees his colleagues and after the coach change in the duty. «The main responsibility now is on us players. The excuse for coaches, if anyone had them, is gone, "said the 24-year-old.

OLYMPIAKOS: The 44-time Greek champions took only one point in the first three group matches. Despite this, Olympiakos is only three points behind Tottenham Second in Group B. In the Allianz Arena coach Pedro Martins wants to "write history". So far, there were Olympiakos in the European Cup without exception defeats against Bayern. The change of coach from Kovac to Flick does not bother Martins. "We do not expect any major differences compared to the first leg. The new coach did not have time to make big changes. We are sure that Bayern will play with the same philosophy, "said the Portuguese.
