A 3-0 triumph at Getafe which sealed their passage to the knockout stages of the Europa League was followed by an emphatic 6-0 win over Werder Bremen in the Bundesliga.
Now, coach Jens Keller wants them to build on those two successes to begin a climb up the league table.
"We have gained self-confidence and we know what we are capable of," he said.
"Every game is decisive for us and with a successful result, we will continue a positive trend and take another small step away from the lower regions of the table.
"We have won convincingly in our last two games so why shouldn't we be optimistic in Kaiserslautern?"
Keller has enjoyed a full week of training without any matches for the first time since he replaced Christian Gross last month.
This has given him the chance to recover some key players from injury and Philipp Degen, Daniel Didavi, Elson and Johan Audel are all in contention for a place in the squad tomorrow.
Kaiserslautern coach Marco Kurz also has another option for tomorrow's match with Stiven Rivic returning to training this week.
"We have tried a few things out in training and I have not yet made my mind up about my team," admitted Kurz.
Almost 50,000 fans are expected at the Betzenberg and Kurz hopes the majority of them go home happy.
"We showed in the game against Bayern what is possible in our home games at the Betzenberg and we have got to play like that again on Saturday," added Kurz.
