Borussia Dortmund chief Hans-Joachim Watzke has warned European giants off young pair Jude Bellingham and Giovani Reyna.
Both teenage midfielders have been linked with Liverpool, while Reyna is also being watched by Real Madrid.
But Watzke is adamant both youngsters will be with the club for the long-term.
He insisted: "We have a lot of young players with us who have a lot of potential. We are currently forming an axis. Bellingham and Reyna are sure to stay here for a long time."
Bellingham has a deal to 2023, while Reyna is in talks to extend his contract which currently runs to June.
