Olympiakos and Panathinaikos completed the regular season of the Euroleague with home wins that confirmed that the Reds finished first and the Greens third, which means they cannot meet again in the tournament before the final.
Topping the Euroleague table with a 24-10 record, Olympiakos defeated Maccabi Tel Aviv 99-93 on Thursday.
The game with the already eliminated Israeli visitors was close, but Olympiakos led for most of the game (by up to 11 points) but Maccabi would not concede till the very end.
