Spartak Moscow Region know there isn't much room for error heading into their EuroLeague Women Final Four clash with UMMC Ekaterinburg.
The European giants have met already this season but in the Superleague Women and the Russian Cup.
In those competitions, teams must have two Russians on the floor at all times.
That is not a restriction in the EuroLeague Women.
Spartak's assistant coach Pokey Chatman, who gained a lot of plaudits last summer after coaching Slovakia and leading them into this year's EuroBasket Women, looked ahead to the class with the Final Four.
"We play them a lot but it's always in the Russian league," she said to FIBA Europe.
"Now, this is the European league, so maybe line-ups change and combinations. You maybe have some ideas that you can put in place. You're not restricted. But the bottom line is they have a roster of great players and a great coach, we have a roster of great players and an exceptional coach."
Aspects to the game that are often overlooked by the casual spectator will determine the outcome of the game, she says.
"I really think the game is going to boil down to those little things that people don't think about," Chatman said.
"Of course D (Spartak's Diana Taurasi) is going to hit a three, Biba (UMMC's Agnieszka Bibrzycka) is going to hit a three, Cappie's going to be tough and the post players are going to be exceptional.
"But I think the team that can execute, slow down and really play the game, shoot some free throws, execute inbounds underneath and on the side out is going to be the most successful team."
UMMC beat Spartak in the Russian Cup and to first place in the regular season of the Superleague Women.
