Franck Sauzee had opened the scoring with a fourth-minute penalty. With the encouragement of that early advantage Marseille committed themselves to attack and, in the 10th minute, Boksic added another goal from a corner kick by Jean Thomas. After 26 minutes, Boksic took advantage of a defensive mistake, breaking clear into the penalty area and slipping the ball into the net.
Roma lost 3-2 to the Turkish side, Galatasaray, in Istanbul yesterday, but still moved through to the last eight of the Uefa Cup 5-4 on aggregate.
Galatasaray, who had lost 3-1 at the Italians' Olympic stadium in the first leg of this third-round tie, were struggling after only eight minutes when Claudio Caniggia, Roma's Argentinian international striker, scored an away goal which effectively killed the tie.
The Turks levelled the leg after 27 minutes through Yucedag Mustafa, but just after half-time Thomas Hassler added a second for Roma, winners of the Fairs Cup in 1961. Mustafa and Erdem Arif scored again, but the Italians held out in a tense final 15 minutes.
