Hertha Berlin coach Jos Luhukay has accepted his share of blame for his side's midweek DFB-Pokal elimination - and vowed not to make the same mistake again in Saturday's Bundesliga clash with Mainz.
Luhukay made nine changes to his starting XI and suffered the consequences with a 3-1 defeat at second-tier Kaiserslautern, but he has promised to field his strongest side this weekend.
``I've got to take the blame for it,'' he said. ``There's a thin line. If you win, then you've done everything right and you receive praise, but it's not so when you lose.
``We don't have just 11 men but we're going to need all of our players this season. We don't have an A and a B team.
``The players had the chance to show what they could do and there was enough motivation for all of them.''
He was not impressed with what he saw, however, and should therefore return to the side he has fielded in his side's previous Bundesliga games as they search for all three points against Mainz, who were also dumped out of the cup in midweek.
Mainz's defeat in Cologne was their fourth in a row, leading their coach Thomas Tuchel to get back to basics.
``We need to take two steps back and start all over again,'' he said. ``We'll throw everything into the mixer to remain ahead of Berlin also after Saturday.
``We made such a promising start to the season and it was unforeseeable that we would be struggling so much a few weeks later.''
Regular goalkeeper Heinz Muller has returned to training and should be part of the Mainz squad, while the hosts will be without the injured John Anthony Brooks, who joins Alexander Baumjohann and Peer Kluge on the sidelines.
