"It was a really good team performance and we wanted to give our supporters something special today," said a delighted Benitez.
"Crouch hadn't played for 20 days because of his nose operation and he was desperate to play and score goals. All of his goals were fantastic and I really liked the move between Pennant and Arbeloa for his first goal.
"To score four goals against a top side is really good and we are fighting hard for that third place. I still think we have played better games this season but I am really pleased with the team today.
"Xabi Alonso and Javier Mascherano controlled the midfield and it has set us up nicely for the Champions League against PSV Eindhoven on Tuesday."
