Borussia Dortmund sporting director Michael Zorc has said extending Christian Pulisic's contract is "not an issue right now."
Pulisic is under contract until 2019 rather than 2018 as previously reported, a source told ESPN FC. He had interested clubs including Liverpool in the summer window.
Speaking to German magazine kicker on Monday, Zorc said BVB were not currently working on a contract extension, adding: "That's not an issue right now."
On Saturday, Pulisic said he was "just focusing on my season... I don't personally deal with negotiations."
He became BVB's youngest ever player in the Champions League on Wednesday and Zorc added: "He has only just turned 18.
"He can be delighted to have made his debut in the Champions League aged 17 and to have set up a goal there as well as having scored and set up goals in the Bundesliga."
Midfielder Sebastian Rode, speaking after the Darmstadt match, told reporters that Pulisic "has unbelievable potential."
And just in case the American sees Major League Soccer in his future, MLS formerly added Pulisic to its allocation ranking list on Monday, the day after he turned 18 years old.
