Reds boss Rafa Benitez began the friendly with a strong side and the game was goalless at half-time. </p> But after several substitutions by Benitez, the Germans took command. </p> The Bundesliga side rattled in five goals from Markus Feulner, Tobias Damm, Ranislav Jovanovic, Chadli Amri and Fatmir Pupalovic without reply. </p> Benitez knows his side will have to improve quickly, telling his club's website: "We know we need to correct things. </p> "We made a lot of mistakes. We need to analyse why things have been going wrong and work hard to fix them. </p> "We can start next week with a new mentality and I am sure we will be much better on Wednesday." </p></font> <br clear="all" /></td></tr></tbody></table></p>
