Marco Reus has urged Borussia Monchengladbach to pick themselves up after masterminding a 5-0 thrashing of his former club with his current side Borussia Dortmund.
Reus arrived at the Westfalenstadion from Monchengladbach in a €17 million deal during the summer, and has enjoyed a steady start to the season with Dortmund.
But on Saturday, the Germany international produced his most explosive display in a yellow shirt so far to haunt his old employers with two goals and an assist in the drubbing.
"This was, of course, a special match for me. I had three wonderful years in Monchengladbach that shaped me," Reus said, also revealing that he had gone to speak to his former team-mates in their dressing-room after the game.
"It's not the easiest time for them. I know them, know how they feel. But it's their job to solve it," he added. "It's important we won this match. This is what we wanted to achieve."
The Dortmund star's second goal was a fine effort as he bent the ball in from a tight angle, and he said: "I've tried to score a goal like this before, but wasn't successful. Today, it finally worked out."
The performances of Reus and fellow youngster Mario Gotze left many in Germany drooling - with the press nicknaming the pair "Gotzeus", while Jakub Blaszczykowski, who set up two goals and scored one, and Ilkay Gundogan ably assisted them in midfield.
"We took about 20 minutes to find our game, to win the fight to play our game," Gundogan said. "We started a little shakily, I suppose.
Gundogan had missed recent matches with a cold, adding: "It was vital I played today after a week when at first I wasn't able to train because of my cold, and to play the full 90, too.
"I've been feeling so much better in training over the last few days and felt going into the game and played really well. I'm fairly pleased. We are all chuffed to have won the game 5-0."
The match included a rare substitute appearance for striker Robert Lewandowski as the Poland international was benched for the first time since March 19 2011 - 62 games ago.
"You really want to play him in every game for the full 90 minutes because he is almost always good for a goal. But the simple fact is that you cannot expect him to play 70 games a season," Dortmund coach Jurgen Klopp explained.
Dortmund visit Manchester City in the Champions League on Wednesday, with some changes likely for that encounter.
Sven Bender played his first minutes of the Bundesliga season against Monchengladbach and could be an option instead of skipper Sebastian Kehl as holding midfielder, while Lewandowski is certain to be back in the starting XI.
