Gerrard's two spotkicks helped the visitors to a 2-1 win.
"We knew what to expect and we got a bit more than we expected - a hot dressing room, a dry pitch and the bus had to park a mile away," he said. "I think they tried everything to upset us.
"It was a good test of our character. We needed to prove that we're capable of fighting for this title and we did that terrifically well.
"They were throwing 70-yard balls into our penalty box from every different angle.
"They have got giants in there who are going up with their elbows and we stood really strong.
"We defended superbly and certainly deserved to come away with the three points."
