Nurnberg coach Dieter Hecking is preparing to meet a number of his former players when they visit Bayer Leverkusen tomorrow.
Philipp Wollscheid became the latest in a line of players to leave Bavaria and move north when he joined Leverkusen in the summer, joining the likes of Jens Hegeler, Stefan Reinartz and Stefan Kiessling in the Westphalian city.
Hecking therefore knows plenty about tomorrow's opponents.
``We're playing against our own branch,'' he said. ``They have four of our former players in their starting team - Hegeler, Reinartz, Kiessling, and lastly Wollscheid.
``It will definitely be a huge challenge. They have not lost in weeks, are in three competitions, and are doing very well.
``They were looking for their rhythm to start with, but now they have found it and are very effective.
``We saw against Bremen how they scored four from five shots.''
Nurnberg's own efficiency has improved in recent weeks with five points from their last three games, which included two local derbies, one with runaway league leaders Bayern Munich.
``Our form is good and the team came through the derbies well,'' said Hecking at a press conference.
``After those emotional derby games, it was great to see us win this week too and be able to move up a gear.''
Victory over Hoffenheim has given Nurnberg a four-point cushion over the relegation zone and taken them to just four points short of their midway aim for the season of 20 points.
Bayer moved up to second in the table thanks to their 4-1 win over Werder Bremen in midweek.
``We'd like to keep this position until the end of the first half of the season,'' said their director of sport Rudi Voller.
Five wins from their last six games, including victory over Bayern Munich, make Bayer the form team in the Bundesliga, and since they have already qualified for the knockout stage of the Europa League, they can now focus on their remaining three league matches.
