After scoring his penalty Gerrard ran to the bench to celebrate with goalkeeping coach John Achterberg.
"I wouldn't like to take all the credit for the three points," said the England midfielder.
"There are so many details that go into the games nowadays. John did a montage on their goalie for me before the game.
"He (Hugo Lloris) consistently went to the right and I think he had saved four out of eight going to his right.
"I was always going to his left having watched that, but if I had never got that montage then I would probably gone to his right so credit to John."
