"When you have top class players, they make the difference. Sometimes it is Torres, this time it was Gerrard," said Benitez.
"He is a player who can change a game on his own. And he certainly did that with his run into the box to create our goal.
"He changed the game. That goal we scored was the real difference for us, that one piece of quality, world class, that changed everything.
"Stevie can do such things. It was a run they could not stop. It could change the whole tie."
