Given that both of these clubs could still finish second, third or even fourth, it’s all to play for in the Principality.
Crvena zvezda beat Trabzonspor 2-1 at home lat Thursday, with two Aleksandars, namely Katai and Pešić, keeping their qualification hopes alive.
Miloš Milojević's team now have six points, all of which have been yielded from matches at Stadion Rajko Mitić.
Monaco meantime were held to a 1-1 draw by Ferencváros in Budapest, despite leading through Wissam Ben Yedder.
So, Philippe Clement’s team are second on seven points, while Trabzonspor and Red Star Belgrade both have six.
In simple terms, if les Monégasques win this one, they’ll rubber stamp second place; Red Star would finish bottom in that scenario.
A victory for Crvena zvezda would guarantee a top three finish, depending on the result in Trabzon, with Monaco potentially slipping to fourth.
There are plenty of permutations but, on the field at Stade Louis II, both clubs must simply concentrate on claiming three points.
