The 33-year-old England captain scored his 100th league goal from the penalty spot three minutes before the break as the Reds twice came from behind to claim a point in a 2-2 draw with the 10-man Magpies.
Rodgers said: "It's a monumental contribution. I have watched him play for many years as a young player and probably for me, his best Premier League goal came at this ground when he played against Newcastle.
"He scored an absolute screamer here from a free-kick. But he's an incredible player and I am fortunate enough that I get to know him as a man as well.
"As a captain, he has been brilliant for me. He understands the manager's role and respects it.
"He is a great player who has got many more goals to come as well. You see his fitness level - people talk about him and his fitness and how is he at 33?
"Well, he's played two really tough international games, played at a high level and he has also got a really good performance in today, so he is still fresh and looking very, very good."
