"It's important not to get carried away," Gerrard told the club's official website.
"We've won nothing yet. It was a massive win and three big points but if we slip up against Portsmouth then those points will be irrelevant.
"To win this league and become champions you have to handle the pressure of being at the top. That's the challenge for us now. Can we handle being top of the league?
"We've done superbly well so far, we're unbeaten, and we have to keep that going now, starting against Portsmouth."
