The 54-year-old coach has disappointed fans by telling them that last season's superb campaign won't be repeated
The 54-year-old tactician masterminded last year's campaign, which saw the club finish in fourth place and qualify for the Champions League.
And after losing over two legs to Dinamo Kiev in a play-off, the former Switzerland international has tried to dampen expectations by explaining that last season was a one-off campaign.
“I can say with certainty that we cannot play the outstanding football we did last season,” he told a press conference on Tuesday. "It is very, very dangerous for us to think that we can.”
New signings Granit Xhaka and Luuk De Jong, however, believe that Champions League football is a possibility for the Bundesliga club this time around.
“I've been playing with Basel in the Champions League,” said Xhaka. “And I can tell you how awesome those nights are.
"I want to be there with Gladbach.”
Similarly, De Jong proclaimed: “This club has some amazing fans, and they deserve to watch the best football possible. Against Kiev we just missed qualification. But my goal is to get there again with this club.”
