Wolfsburg contacted UEFA ahead of completing a deadline day transfer for Andre Schurrle, with the Bundesliga club currently under investigation regarding financial fair play (FFP).
Wolfsburg, who are owned by German car manufacturer Volkswagen, paid a reported transfer fee of 32 million-euro plus bonuses to secure Schurrle's return to the Bundesliga from Chelsea.
The 24-year-old Germany international has become the latest addition the Wolves' squad, who, without playing in the Champions League, have brought in the likes of Luiz Gustavo from Bayern Munich and Kevin De Bruyne from Chelsea in recent transfer windows.
A report in Die Welt on Tuesday added up Wolfsburg's transfer balance to minus-108 million euros since the turn of the decade -- the second-biggest deficit after Bayern Munich, who, however, can weigh two Bundesliga titles, two German Cups and a Champions League trophy against their investments.
Earlier this month, Wolfsburg sporting executive Klaus Allofs confirmed in kicker that the club are currently under FFP investigations by UEFA.
He said that he was convinced that "the model Wolfsburg will be met with approval" and warned that, should that not be the case, it was also mean that Bayern "cemented their supremacy not only from a sporting but also an economical perspective."
Speaking to ZDF TV following the Schurrle transfer on Monday, Allofs said that Wolfsburg contacted UEFA ahead of the completion of the deal.
"We have been dealing with it [the FFP] in the past few weeks," he said. "We are of course in contact with UEFA, and have filed the necessary documents, and have also contacted them ahead of this transfer. We are indeed prepared."
Allofs continued that he does not expect any problems with UEFA, saying that the club would have not done the deal with Chelsea otherwise.
"Everyone got what he wanted with this deal," Allofs told reporters of the transfer on Monday. "We add a lot of quality to our squad. Andre is firmly established in the national team, is in the best age.
"He is dangerous in front of the goal and he is fast -- those are his most prominent features. He can play on both wings, and as the false No. 9."
On Tuesday, Schurrle trained in Wolfsburg and will meet up with his new teammates on Wednesday, once they return from their away match at Frankfurt.

Meanwhile, Schurrle's former clubs Mainz and minor league club Ludwigshafener are set to benefit from the multi-million-euro transfer.
Both teams are due a portion of the transfer windfall, with Bundesliga side Mainz expecting some 750,000 euros according to the club's sporting director Christian Heidel.
"For all we care, he could return to England in a 50 million-euro transfer next season," he was quoted as saying by SWR.
Ludwigshafener, the club Schurrle left as 15-year-old, will also receive a six-figure sum, with Heidel telling Sport Bild: "They will now build their next club home."
