Borussia Dortmund are pushing to advance contract talks with Jude Bellingham.
Football Insider says Dortmund are worried about Liverpool's interest in the England international.
Bellingham, 18, is already contracted until 2025.
But Dortmund want to offer him a better deal in the hope he will resist Liverpool.
The German club have also considered signing Bellingham's 16-year-old brother, Jobe, who made his debut for Birmingham last month.
Manchester United and Chelsea have also been linked with Bellingham.
