Aulas commented on a tweet linking Dembele with a move to the Serie A champions and ruled out letting the 23-year-old leave the Ligue 1 side, per Calciomercato.com.
"Lyon are not interested in any offer for Dembele," he wrote. "He is one of our symbols of the new project. No Manchester United, no Juventus: it is a matter of principle, and not of price."
Serie A champions Juventus are keen to bring Dembele to Serie A and sent scouts to watch him in action during Lyon's 6-0 win over Angers, according to Mark Walker at the Daily Record.
