Wolfsburg boss Dieter Hecking says the DFB Pokal winners want to "continue to annoy" Bayern Munich after signing Dante and Julian Draxler before the end of the transfer window.
Wolfsburg finished runners-up to Bayern in the Bundesliga last season as well as winning the cup, and their victory over Pep Guardiola's men in the German Super Cup in August prompted discussion as to whether they could challenge for Bundesliga supremacy.
The Volkswagen-owned club have spent heavily in recent years, bringing in big names like Luiz Gustavo and Andre Schurrle, but they agreed to sell key stars Kevin De Bruyne and Ivan Perisic at the weekend after they both expressed a desire to move on.
Die Wolfe reacted quickly, though, bringing in Germany international Draxler from Schalke and former Brazil centre-back Dante from Bayern, and Hecking believes his side can still be contenders.
"We want to continue to annoy Bayern," Hecking told reporters as the new signings were presented at the Volkswagen Arena.
Draxler, who was also a target for Juventus, is reported to have cost €36 million and his transfer was the most expensive outside the Premier League this summer.
While the 21-year-old has struggled for form and fitness over the last two years, Wolfsburg sporting executive Klaus Allofs has labelled him a "top-shelf" player.
Hecking added: "As the coach, you always think through the players who could suit an attacking style of play, and when you do that you land at Julian Draxler relatively quickly.
"His meteoric rise in recent years didn't just come out of thin air -- Julian really has something special.
"When he makes a burst from the midfield with his ground-covering strides, he is extremely dangerous, and he also has a strong finish. He is flexible and can be used in a variety of attacking positions."
Draxler said on Tuesday that he is hopeful the move from Schalke will reignite his career.
"It's my first time away from familiar surroundings, but I think that's the only way for my character to develop in every area," he said.
"I had great expectations but was stopped in my tracks by injury. I didn't manage to make the developments I intended to. That was the reason I had the desire to make a change."
Former Borussia Monchengladbach defender Dante, 31, has also struggled for form recently and fell down the pecking order at Bayern despite Pep Guardiola having to contend with injuries at centre-back.
Hecking said: "It's important to us to be well covered in all positions. For that reason, we wanted a fourth, strong central defender, which we have found in Dante. His qualities are well known.
"He is a left-footer, which is something of a rarity for a central defender, but is important in opening the play. He can play with both feet, though. He is strong in the air and dangerous in front of the opposition goal.
"I extensively observed him during his time at Gladbach and considered him to be a player that could be a great asset to many teams, with his style of play and charisma."
Dante, who had joined Bayern in 2012, said he spoke to compatriots Gustavo and Naldo before making the decision to move to Wolfsburg.
"They had a part to play in my transfer," Dante said. "They spoke very, very positively about VfL and said that the team is a really good group."
Asked about his departure from the Allianz Arena, he said: "Bayern was a nice story. I no longer want to talk about it, but naturally I am a bit disappointed, because I have always identified with my teams."
Meanwhile, Allofs said Wolfsburg addressed any concerns over financial fair play over the summer, having made a €44m profit despite having invested €55m in the squad.
De Bruyne alone saw the club receive around £54m (€73m) and Allofs said: "The money we had has been well spent. We want to work well economically, and have emphasised that.
"We also had the financial fair play provisions. We've left that problem area with Kevin's transfer."
