Red Star Belgrade and Olympiacos face off in the Serbian capital tonight in what is already a must-win match for both teams.
With Bayern Munich and Tottenham battling it out in north London at the same time, this match is a golden opportunity for both Red Star (Crvena Zvezda) and Olympiakos to make an early play for a potential last-16 spot.
With Olympiakos already fighting back to claim a 2-2 home draw with Spurs, the Greeks will be confident of building on that result in Belgrade - though Red Star will be looking for a performance after falling 3-0 to Bayern in Germany.
