RB Leipzig chief executive officer Oliver Mintzlaff says he is tired of hearing speculation about Emil Forsberg and Naby Keita, as the duo are not for sale.
Europe's elite clubs have been lurking around last season's Bundesliga surprise package, with Arsenal and Liverpool expressing interest in Forsberg and Keita respectively.
The Bulls, who finished runners-up in the league and qualified for the UEFA Champions League, issued a hands-off warning for both stars.
"That topic is boring," Mintzlaff told reporters when asked about their futures. "It's only our second Bundesliga season, our squad's still the youngest and most likely also the most inexperienced.
"It would be great to start where we left off. It's an advantage that there's no upheaval."
