The Russian outfit got their first victory in this season’s Champions League to end a four-match winless run in all competitions and nearly 400 minutes without a goal, but Slutskiy insisted that there was still work to be done to get his team back firing on all cylinders.
"I'm afraid we can't pass through the crisis in two or three days," Slutskiy, 42, told reporters. "It was a really nervy match. It's obvious we're on a bad run, so we just had to win. Today was not about Viktoria, it was all about us.
"It was a really nervy match. It's obvious we're on a bad run, so we just had to win. But I can't say our life is great right now.
"The break in the league comes just in time and we hope our injured players will return to full fitness. We'll fight and try to prove we're Russian champions for a reason."
CSKA conceded from Frantisek Rajtoral’s strike after only four minutes, but goals from Zoran Tosic and Keisuke Honda put them back into a lead that they never relinquished, and Slutskiy praised his players for orchestrating the comeback.
"The start was very frustrating but the lads deserve credit for turning the game around in this situation, when all nerves and energy are gone," he continued.
"The match scenario was far from ideal for us, but we won and I'm delighted about that."
Plzen boss Pavel Vrba was incredulous that his team failed to take their chances in the game, lamenting that they were victims of their own mistakes.
"We started well and had two or three chances to score, but we could not," he explained. "Then we conceded goals from situations which we had prepared for, because of mistakes with our passing.
"I must praise my players' efforts in the second half and for fighting until the end for a point, but we made it hard for ourselves. Sadly our own mistakes brought about the result. The situation we are in now is very difficult."
CSKA’s win sees the pick up an important three points in their quest to qualify from Group D, which also contains Manchester City and reigning champions Bayern Munich, but Plzen are in danger with no points from their first two games.
