The 18-year-old, who officially joined the Londoners in the summer, was sent on a season-long loan to Germany to gain valuable experience and regular playing time in the Bundesliga, aiding his development.
The teenager has impressed during his time there, and the club’s sporting director, Claus Costa, has expressed confidence, saying he has no concerns about Vuskovic’s future.
"We had very constructive discussions with Tottenham; they’re a top-professional club, judging by the communication with loan manager Andy Scoulding,” he told Transfermarkt.
“They’re closely monitoring the player, which shows how they assess Luka. Tottenham isn’t interested in weakening us or ruining the loan.
"It’s understandable that they’re trying to protect themselves against possible worst-case scenarios. Otherwise, I don’t want to comment further.
“I believe Tottenham also knows how good the situation here is for Luka. That’s why I hope we never get into a situation where we have to think about anything else."
