A late goal from Lucas Ocampos secured Marseille a 1-0 win at Nantes to maintain their 100 per cent start to the new Ligue 1 campaign.
Rudi Garcia's men had seen an effort from Florian Thauvin ruled out for offside before Maxime Lopez sent an effort just wide.
The visitors, though, made sure they left La Beaujoire-Louis-Fonteneau with all three points when Argentine midfielder Ocampos slotted in a rebound with just two minutes left.
However, there was still time left for Nantes striker Emiliano Sala to head a late chance only just off target as Claudio Ranieri's side were left to reflect on a second straight Ligue 1 defeat.
