Coach Nathan Brown says that he would like to see Lachlan Fitzgibbon continue to improve his game after signing a new contract.
The 24-year-old's strong running game and his ability break through opposition defences has made him one of the most threatening second-rowers in the competition.
But the nib Newcastle Knights coach believes he's only scratching the surface of his potential.
"Last year was quite clearly his best year," Brown said

"Over the course of the three years, I've seen him go from where he was to where he is now.
"Now he's starting to get that confidence, now he's got a new contract and now we want Lachy to keep improving and that's key for us. The last thing we want is for him to be satisfied where he is at."
Forming a lethal combination with Kalyn Ponga, Fitzgibbon has burst onto the NRL scene with a strong sense of finding the try line, crossing for 17 tries over last two seasons.

And Brown believes he can take his game to the next level.
"We all saw the combination that him and Kalyn built together, he's ability to score tries for a backrower is probably as good as any other backrower in the competition," Brown said.
"Two years ago, when we got the wooden spoon, he still scored more tries than any other backrower in the competition bar one.
"As good as he was last year, I really think he can go to another level."

Brown said that Fitzgibbon could have tested his market value but wanted to stay with the club where he made his debut back in 2015.
"It's a good signing and it's great for the club," Brown continued.
"He's a local junior and he wants to be here which is important.
"He signed a contract which was fair for both parties and if he really wanted to he could've tested the market but he didn't."
