Albion’s European adventure is becoming less enjoyable as two goals in two minutes – from Chancel Mbemba and Jordan Veretout – put the French side in front.
A bizarre moment then followed when Albion were awarded a penalty by VAR only for the referee to change his mind seconds later and award Marseille a free kick.
Ansu Fati, with a header, and Danny Welbeck have gone closest for Albion.
Despite the scoreline, the 2,800 travelling Seagulls supporters have been making their voice heard among the 63,000 fans packed into the Stade Velodrome.
