Werner will become a Chelsea player on July 1 following his £47million move, even though Leipzig’s season won’t have finished by then.
With football across Europe having been postponed by the coronavirus pandemic, the final round of the Champions League will be staged in Lisbon, Portugal in the form of a mini tournament, from August 7.
While many out-of-contract players have agreed short-term deals to complete their seasons are their respective clubs – Chelsea’s Willian and Pedro are two such examples – Werner will instead join up with his new club.
"Of course it hurts me that I can't help out [RB Leipzig] to play in the Champions League," Werner told Sportbuzzer. "But I'm a Chelsea FC player from July 1st and I'm being paid by Chelsea from then on."
"It was clear that all parties - Chelsea, RB and my side - should and must settle this. Of course I tried to keep out of the Champions League issue as much as I could because it was clear that I would have to hurt one side. That's why my agent finally agreed it with the clubs."
But while Werner won’t be on the pitch to help Leipzig, he hopes he can be in the stands to support them.
"I am forever connected to Leipzig and RB, will sit in front of the TV during the quarter finals and keep my fingers crossed - maybe I can even be on site in Lisbon," Werner added.
