The Anfield side were beaten 3-1 by fierce rivals Manchester United in the final of the International Champions Cup in Miami on Monday after both teams came through their respective groups.
Brendan Rodgers' side were beaten 1-0 by Roma in their first game in America - a game that was part of the ICC - before victories against Olympiacos, Manchester City and AC Milan saw them through to the final of the pre-season friendly tournament.
Liverpool travelled to the likes of Charlotte, Miami and New York during their visit and were continually greeted by hordes of supporters eager to get a glimpse of the Premier League stars.
And speaking to the club's official website, Gerrard explained how the support of the US fans only highlighted the size of the Merseyside club.
He said: "The support we have had over the past couple of weeks has been phenomenal as usual. [Two hundred thousand fans] is staggering."
"You only have to go back to last year in Asia with the numbers [who came to watch us] as well, which just goes to show how big this football club is. It's down to the players to deliver over the season and try and make them happy with a trophy."
"The lads have been working hard and training well with all the work outs and the tests we have had the last couple of weeks. It will put us in good stead for the season, but of course it's still disappointing to finish the tour when you lose to Manchester United."
"We've been building and getting better as the games have gone on. For 55 minutes against United I thought we were very good, and then obviously we tired a lot and Manchester United made us pay."
Liverpool conclude their pre-season preparations with a visit from Bundesliga giants Borussia Dortmund on Sunday before beginning the new Premier League campaign with a game against Southampton on August 17.
Rodgers was forced to work without Daniel Sturridge against United after the England international picked up a slight knock before flying home, but the 21-goal striker is expected to be fit for the visit of BVB.
Meanwhile, Dejan Lovren is also likely to play some part against Jurgen Klopp's side after he signed from Southampton last month for around £20 million.
