Toiling quietly behind leaders Bayern Munich and surprise package Eintracht Frankfurt, Bayer Leverkusen have returned to the form which took them to a league-cup double last season. Xabi Alonso's side, who travel to mid-table Augsburg on Saturday, may be seven points behind Bayern but are the only side which truly stokes fear into the German giants' hearts. Leverkusen torched all before them last season, breaking through for a first Bundesliga title without losing a game -- something no other team, not even Bayern, had done before.
