Preview Report LEVERKUSEN, December 16 (Bundesliga) - Michael Skibbe leads Bayer Leverkusen into the winter break far from satisfied with his first few months in charge of the club. Bayer, who entertain Hannover on Saturday, are currently 11th in the table and closer to the relegation zone than the European places. Yet Skibbe's opposite number, Hannover coach Peter Neururer, finds that hard to believe. ``They should be a top three side, but the table never lies,'' Neururer said. Bayer's disappointing position can be attributed to a series of poor defensive displays this season. In 16 Bundesliga games, Bayer have failed to keep a single clean sheet. Doing so on Saturday is a priority although three points remain the focus. ``The team have not shown their true potential in the last three games and, although Hannover are on the up and a difficult opponent, we have got to win at all costs,'' said Skibbe. Bayer have not won in their last four games, but have only lost one of six home matches against Hannover. Skibbe will have to make changes in defence with Roque Junior missing out due to an Achilles tendon problem while Carsten Ramelow is suspended after picking up his fifth yellow card of the season in the 1-1 draw with Nurnberg last weekend. Hannover, in 10th, are turning the corner and are yet to lose under new coach Neururer. They have two wins and a draw in their last three games and will be hoping to continue that good form against Bayer. Former Bochum coach Neururer said: ``Bayer are undoubtedly under pressure to get the three points and we will give all we can to win.'' Silvio Schroter misses out after breaking his foot while Hanno Balitsch is also struggling to shake off a thigh strain. Should Balitsch not be fit, Neururer may be forced to alter the system rather than move a player out of position like he did last weekend. Neururer admitted: ``The idea of putting (striker) Michael Delura at right-back was not the best.''
