Isac says everything went to plan as Brazil move into another World League final
"I think the game was very focused for us from the start. We put pressure on their serve and in the match we managed to do our strategy that we studied, and this was fundamental [to victory]."
"At the end of the third set we made some mistakes, they took more risks and the game became a little more difficult."
Isac received his first starting call from Brazil coach Bernardinho as middle blocker Eder was having knee problems, but was happy to take up the challenge.
"When you get the opportunity to play, you give everything. I train to give my all and I did the most I could do."
"Eder was feeling his knee yesterday and today he confirmed, but I felt ready. You are always a little nervous and anxious, and when you go to the court it lowers a little - there it's emotion, but you have to stay strong and focussed."
He also expects to play a part in the final as Brazil look for their 10th World League title.
"We know Russia very well. We will prepare in the best way possible, watch the film to see their things so we can neutralise them, and play the game, and leave with an important victory."
