The Reds won 2-0 at Sunderland on Saturday thanks to first Premier League goals from Mohamed Sissoko and Andriy Voronin.
"It was really good, really important for us," Benitez said of the victory. "The team showed character. We had chances that maybe could have been in before (the second goal) but in this period when everyone was talking about our performances away last season, I think it was really important to win the match."
