"I wasn't really aware that this was my 300th league game until a couple of days ago so it was a really proud day for me," Gerrard told the club's official website.
"It only seems like a couple of days ago that I made my debut so I'm really proud to clock up that many appearances.
"I love playing football and I love playing for this football club. I've still got a load of goals, a load of ambitions and stuff to achieve here and that's what drives me on.
"Obviously, I'd love to win the league and win more trophies.
"Playing with top players and being coached by a top manager - that also drives me on."
