Borussia Dortmund have been better off since the departure of head coach Jurgen Klopp, according to Stephane Chapuisat.
Liverpool's 1-0 defeat to Manchester United has left them eight points adrift of the Champions League places, with Klopp only managing to take nine points from his first seven home matches since taking charge.
"It was a good time to make a change after seven years. Players who nobody believed in any longer have blossomed," he said, as quoted by Sport Bild.
"Jurgen Klopp probably felt it himself. It was simply the best for both parties.
"The most difficult thing [for Dortmund now] will be to keep all their players in the summer, so they can attack Bayern again."
"Dortmund against Basel would be a very nice final, but when BVB get there, I wouldn't mind who they played," he added.
