OM still without answers after Toulouse draw
Didier Deschamps' men created almost all the openings of note but left with just a point, and both sides ended the game with 10 men as Charles Kabore saw red for the visitors in the 58th minute and Etienne Capoue was dismissed for the hosts late on, both for second bookable offences.
One positive note for Marseille was the return to action of former Toulouse striker Andre-Pierre Gignac as an 82nd-minute substitute following a month out with injury which has also included a spell at a weight-loss clinic.
Rod Fanni was the first to go close in the 13th minute when his shot was parried away by Toulouse goalkeeper Ali Ahamada and seconds later Benoit Cheyrou was unlucky when his long-range shot crashed off the bar after taking a deflection off Aymen Abdennour.
Cheyrou threatened again six minutes before the break as Ahamada was forced to punch clear another thunderbolt and the goalkeeper did well again to keep out Andre Ayew's volley following a Cheyrou free-kick as the half drew to a close.
Kabore was sent off for a rash challenge on Daniel Braaten to dent Marseille's hopes of victory and another chance went begging for OM in the 79th minute when Lucho Gonzalez fired a shot just off-target after superb approach work by Jordan Ayew.
Seconds later Ahamada was called upon again to deny Andre Ayew after the Ghanaian had teed himself up for a volley.
Toulouse then had Capoue sent off in the final minute of normal time before creating their solitary chance of note three minutes into stoppage time as Franck Tabanou's free-kick drifted wide.
