Spurs have been linked with a January swoop for the 20-year-old, who has 18 months remaining on his contract at the Ligue 1 club.
But Martin insists there has been no solid interest from the North Londoners or Serie A club Fiorentina, who are also believed to be keen on the France Under-21 international.
He told calciomercato.com: "Fiorentina and Tottenham chasing Haidara? There are many clubs interested in him, but for the moment we have not received concrete offers."
Martin also played down speculation Haidara's agent has met with Fiorentina officials over a potential move.
The sports director added of the defender, who has also previously been linked with Aston Villa: "I don't know. I only know that the press have put out many declarations, but for now Massadio remains a Nancy player."
