Real Madrid midfielder Toni Kroos defended Zinedine Zidane, pointing to the club's trophy haul under the coach.
But Kroos dismissed any criticism of Zidane, who has led Madrid to eight trophies since taking the helm at the start of 2016.
"In a team like Real Madrid, arguments always arise when things are not going well," Kroos said, via Marca .
"Zidane has won eight titles in two years, that's more than enough."
A double from Cristiano Ronaldo helped Madrid to their first-leg win over PSG, putting them on track for the quarter-finals.
Kroos talked up the importance of the Champions League, a competition the La Liga giants have won the past two seasons.
"We have gone through a difficult phase, but in recent weeks we have raised our level and I am confident that we will be very successful going forward," he said.
"This victory is very important because the Champions League is the only competition we can win right now.
"Although I didn't feel all of the pressure was on us because we won the last two. We are Real Madrid, so it's always there."
Madrid travel to Paris on March 6 for the second leg of their last-16 tie and face four league matches in the meantime.
