Moller said that Gladbach's home form, eight wins from a possible nine, will make the match competitive between the likely champions and Champions League hopefuls.
"Two really strong teams are set to go head to head in Monchengladbach, and FC Bayern remain the top favourites to win the league," he told Bundesliga.com.
"Gladbach are strong again, though, and they're fighting for a place in the UEFA Champions League so it's going to be an interesting encounter and it's not going to be such an easy game for Bayern. Gladbach are strong at home and this is an intriguing game to get the second half of the season underway."
Bayern are currently top by seven points with a game in hand, while Gladbach are third.
