With an FA Cup semi-final against Manchester City to come on Sunday and the fight for Champions League qualification hotting up, Benitez refused to question his players' passion for the cause and said it was a good thing to see them arguing on the pitch.
Chelsea became England's last remaining representatives in Europe when they moved into the semi-finals of the Europa League despite a 3-2 defeat on the night as Premier League rivals Tottenham Hotspur and Newcastle United both stumbled out.
"It's always good to have players arguing about things that happen on the pitch so you can correct these things at half-time," Benitez told reporters.
"We were talking about that, adjusting positions, so it's fine. Not a problem."
Chelsea never looked in any real danger of exiting the competition but the defensive issues that enabled Rubin to come out on top on the night gave the Spanish coach cause for concern ahead of Sunday's FA Cup clash with City.
With centre-back Gary Cahill and left-back Ashley Cole out injured and Branislav Ivanovic left on the bench, the Russian outfit breached Chelsea's rearguard twice with simple crosses from the flanks.
"FIRE AVB!"
"I'm disappointed because we didn't defend well in the second half but we go through and I'm really pleased with the team and the effort, the players gave everything on the pitch," Benitez said.
"I'm happy with the first half, but we have to improve on the second half, not just the defenders but the whole team. We have to deal with crosses better, but you have to give credit to them as well because they have some players with quality."
Their manager Andre Villas-Boas hailed his team as "heroes", but the club's former chairman Alan Sugar called for his head.
"AVB should be fired," he said on Twitter, borrowing a catchphrase from his own show "The Apprentice".
