Liverpool fielded five derby debutants in their starting line-up and the introduction of Sebastian Coates made it six when he came on at half-time.
The average age of the Reds team on Sunday was just under 25 with the likes of teenagers Raheem Sterling, Suso and Andre Wisdom included.
"I feel sorry for our lads because I thought we were fantastic and deserved to win," said Gerrard.
"We had a young, small team out there but they were all men and stuck together.
"There was one team here who came to play football and win the game and that was us."
