Juantorena was injured at the start of second set (score was 4-1 for Lube). He clashed with Simon after a block.
Because he acted like he broke his pelvis, Fefe took him out and never gave him another chance despite his continues requests.
As you can see at the end of the match, there was an argument between coach and player
Yeah. that's reason why Lube had been struggling since set 3. Monza deserved applause as well. They played tough even without Oleh.
