|Natalia Vieru was dominant for Sparta&K in the paint|
The former champions had to overturn a double-digit deficit to complete the series win, in what was a much improved performance by Sopron after being overwhelmed during the first meeting.
Tikhonenko walked off the court having gathered a season-best haul of 16 points and 15 rebounds, whilst Vieru accumulated 11 points and 15 boards as Sparta&K completely dominated on the glass.
However, during the early stages, the home fans were dreaming of their favourites forcing a third and deciding game back in Vidnoje after their favourites set the early pace.
With the game locked at 14-14, Igor Polenek watched contentedly as his team's confidence returned when they scored ten points without reply in an exciting surge during a super spell across the first and second quarters.
However, the visitors responded in real style with an even more potent run as they posted a devastating 24-6 burst to put them onto the front foot.
Sparta&K then locked down Sopron after the break, holding them to single digits during the third quarter, which gave them the platform they needed to eventually cruise to victory.
Zsofia Fegyverneky had an impressive 19 points in defeat and her Sopron team-mate Sara Krnjic also did her best to inspire a home win by posting an efficient 11 points and seven rebounds.
Igor Polenek, Uniqa Euroleasing Sopron coach:
"Congratulations to Sparta&K, and good luck to them in the Final-8! I'm proud of my team too, we had a good season in the EuroLeague. Today, as in the whole season, they controlled the rebounds, and this was the key."
Alexander Vasin, Sparta&K MR Vidnoje coach:
"We are very happy that we are in the Final-8, following on the great tradition of our club. Today it was much harder than on Tuesday. Sopron took a 10 points lead, but our players remained strong, and turned the game around."
Zsófia Fegyverneky, Uniqa Euroleasing Sopron:
"I'm disappointed, because we lost, but also proud, because we played in the play-offs again. Before the season, except perhaps us, thought that it was possible. This is a big thing. As for the game I will only say one word: rebounds!"
Evgenia Belyakova, Sparta&K MR Vidnoje:
"We are very happy that we advanced to the Final-8 needing only two games.We felt very well today on the court, the atmosphere was beautiful here, in Sopron."
