Mouloukou Diabate sunk two free-throws with three seconds remaining to give Roanne Basket a thrilling 68-66 home victory against Antwerp Giants in the battle for top spot in Group L.

The visitors trailed for almost all the game, but outscored Roanne 16-8 in the final seven minutes to set up the thrilling climax.

The visitors opened the second half with a 7-0 run capped by Roel Moors' trey to tie the game, and it took until the 5:31 mark for Roanne to break their duck when Mims drained a three-pointer.
The game remained tight, but a Noel jumper set the home team into the final break with a 51-44 lead, and they looked on their way to victory before Giants scored 11 unanswered points capped by Gay's trey to set up the thrilling finish.
Uchenna Nsonwu led all scores with 22 for the hosts, with Gay topping Giants on 20.
"With this win we finish top of our group. That's important. We are the only French team still in the tournament. We did not play good in offense, we were miserable really, without rhythm. We knew that we were already qualified and it's never easy [to play] when you know that."
Mouloukou Diabate, Roanne player:
"I should have missed my second free throw [at the end] because there was still only two seconds left. We missed a lot of shots in the game."
Eddy Casteels, Antwerp coach:
"We came here to win, even if we knew we were already qualified. [We lost] but they scored only 68 points at home so it's not too bad. It's not the first time that we play so bad in the beginning and then we have to fight to stay in the game. You spend a lot of energy to do that, but [the good thing is] we stayed in the game tiil the end."
