Usain Bolt says there's zero chance any non-athletics athlete can beat him in a race but welcomes Pierre-Emerick Aubameyang's challenge.
Borussia Dortmund are set for talks with Pierre-Emerick Aubameyang in the "next weeks" to get clarity on the forward's future amid links with Chinese Super League club Tianjin Quanjian.
Aubameyang, 27, is under contract at the Westfalenstadion until 2020, but he has been linked with making a move away from the club after the DFB Pokal final on May 27.
Paris Saint-Germain, AC Milan and Manchester United have also been mentioned as potential destinations for the Gabon international, while it is reported the Gabon international could be offered a weekly salary of around €500,000 and Dortmund a transfer fee exceeding €80 million.
"We have nothing on hand," BVB sporting director Michael Zorc told kicker "We'll hold talks in the next weeks."
Even if Aubameyang leaves the Westfalenstadion, Dortmund do not plan to bring in a high-profile attacker to replace him, kicker referring to recent social media rumours linking Real Madrid's Alvaro Morata with a switch to the Bundesliga club.
With head coach Thomas Tuchel's future at the club still unclear, Dortmund continue their planning for the new season. Earlier this year, BVB announced the signings of Gladbach midfielder Mo Dahoud and Bayer Leverkusen defender Omer Toprak.
Pierre-Emerick Aubameyang has scored 29 Bundesliga goals this season.
And Toprak's arrival at the Westfalenstadion could also mean the end of Germany international Matthias Ginter's three-year spell at the club. The defender has strongly been linked with a switch to Hoffenheim where he could replace Bayern-bound Niklas Sule.
On Thursday, Bild reported that Hoffenheim and Ginter have already agreed personal terms, and that Dortmund are holding out for a transfer fee between €15m and €20m. However, Zorc said that "we have yet to receive an official bid for Ginter."
On Saturday, Hoffenheim and Dortmund compete for the last automatic qualification place for next year's Champions League season. Both teams have 61 points and conceded 37 goals, but Dortmund not only have a superior goal difference by four but also won the direct duel.
Ahead of the final match of the Bundesliga season against Werder Bremen, Zorc said in kicker that finishing third "has our clear priority and we are not considering other scenarios."
BVB CEO Hans-Joachim Watzke said competing in Champions League was of "the greatest importance" for the club as it would give Borussia "planning security."
