Jurgen Klopp is confident that Borussia Dortmund have what it takes to cope with the departure of some of their star players in the summer transfer window.
The Champions League runners-up will lose Mario Gotze to Bayern Munich, while Robert Lewandowski seems to be on his way to the Bavarians as well.
Nevertheless, Klopp has little doubt that BVB will sign adequate replacements for the players who leave for greener pastures.
"I have read that a difficult season awaits us, but that's nonsense. We have a lot of quality and a steady foundation," Klopp told Bild.
"There will obviously be a few changes as some players will leave. I think the changes will benefit us, though, and I am quite optimistic.
"I can't say how many players we will sign, but we are working on it. I can guarantee that everything will be fine in the end. Plenty will happen in the next few days and weeks."
BVB already announced the signing of Sokratis Papastathopoulos from Werder Bremen on Tuesday, while Felipe Santana's departure to Schalke has been officially confirmed since the Champions League defeat too.
