Gerrard does not believe Rafa Benitez' squad needs an overhaul, but that quality players are needed to close that gap again.
"There are teams that have grown significantly in recent times, like Chelsea. In addition, Manchester United have been too strong [for us] for many years," Gerrard is quoted as saying in the Daily Mail.
"Last year we came close to beating them but it is very difficult to overcome such a powerful team.
"Everyone knows that we must learn from this season. Some players have said we need a stronger squad and the key is to have better players and improve. I do not believe in profound changes or a revolution. Three or four quality players should be enough but more quality than quantity.
"The Premier League is the food of this club. We haven't won it for such a long time and the crowd demand it.
"They want us to win this more than any other competition. We must continue to fight for this, hopefully finishing fourth this season and having a real go next season.
"After finishing second last year we started this season with the idea of winning the league and the Champions League.
"After a series of bad results we had to change targets. Now the fans are desperate for us to win the Europa League. It's the only trophy left for us to fight for and we want to win it."
