Fuster scored the lone goal in the 72nd minute for the Greek side, but Russian
side Rubin was on the spot just minutes later after starting goalkeeper Balazs
Megyeri was sent off for a foul on Gokdeniz Karadeniz in the area.
Carroll replaced Megyeri in goal and, with his first touch, saved the penalty
from Bebras Natcho and 10-man Olympiacos held on for the huge road win in the
first leg of the series.
Also Tuesday, Tomas Sivok and Simao scored after Braga had Helder Barbosa sent
off inside the half-hour, and Turkish squad Besiktas won at Portugal's Braga,
2-0, in the first leg of their round of 32 series.
The remainder of the final 32 series kick off Thursday, with Manchester United
at Ajax and Manchester City at FC Porto highlighting the day's action.
