The Royal Blues have endured a tough return to the top flight. After their 3-1 defeat to Koln on the opening day, they have played out back-to-back draws, most recently holding on for a goalless one against Wolfsburg.
Schalke have picked up just two points from a maximum of nine and sit 13th in the league standings. They will look for their first win of the season when they play this weekend.
Berlin, meanwhile, have begun the season well. They picked up a 2-1 win over RB Leipzig in their last outing. Strike partners Sheraldo Becker and Jordan Siebatcheu combined to hand the Iron Ones a two-goal lead in the first half before their opponents scored a late consolation.
The visitors sit third in the points table with seven points from three games and will look to continue their winning ways.
