Red Star Belgrade used a bit of luck to come away with a point against Napoli in its long-awaited return to the Champions League on Tuesday as it held the Italian club to a 0-0 draw.

Napoli forward Lorenzo Insigne hit the crossbar early on, Red Star goalkeeper Milan Borjan did well to stop an effort from Arkadiusz Milik, and defender Milan Rodic cleared an attempt from Napoli's Jose Callejon off the line midway through the second half.

In the other Group C game, Liverpool beat Paris Saint-Germain 3-2.
