Having to cross swords with Shakhtar followed by challenging league tasks against Dortmund and Moenchengladbach and Real in the second group F encounter might make Tedesco meet his limits.

Next to demands to become Germany's number two behind Bayern Munich, international attention is a vital part of the club owner's business model as the energy drink manufacturer is regarding itself as a global player.

Next to football, the company is well-established in all sorts of adventure sports.

Having won the 2022 German Cup and reached the Euro League semifinal has triggered vast expectations to continue the successful journey.

Former Moenchengladbach director Max Eberl, seen as one of Germany's leading management figures, is said to join in but negotiations turn into a cliffhanger as Eberl's former club is demanding a significant transfer fee.

New arrival, Chelsea's Werner, might lose his place in starting eleven to Silva while Szoboszlai and Forsberg are said to make their way into the starting line-up next to support Leipzig's top star, French international Christopher Nkunku.
