Schalke 04 midfielder Leroy Sane is expecting a difficult test when his side come up against the in-form Borussia MG this weekend.
The Konigsblauen travel to Borussia Park on Sunday to take on a Gladbach side who are on a four-match winning run in the league.
The Gelsenkirchen club are also on a good run having won four of their last five league outings.
Both sides drew in their European games in midweek and Sane believes Schalke will have to be at their best against the resurgent Borussia Monchengladbach.
"Gladbach are on a great run at the moment. They're very dangerous going forward and we'll have to be on our toes," he told the press ahead of the game.
"They're a tough nut to crack, but we're all looking forward to the game. We'll prepare well and I’m sure that we’ll get a positive result."
