The Kenya international was expected to have signed with Club Brugge by today, but now could end up in France.
OM chief Andoni Zubizarreta is in the market for a late midfield signing and he is today moving for Wanyama. Barcelona's Rafinha is also being considered.
Zubizarreta would prefer to take Wanyama on-loan, though Spurs favour a straight sale.
Spurs and Club Brugge had agreed a fee of €13m for the midfielder last week.
