Former Kangaroos and Blues hooker Robbie Farah believes second row enforcer Tyson Frizell will be the signing of the year in the NRL.

Frizell has linked with the Newcastle Knights from St George Illawarra with the Knights eying back-to-back finals appearances.

“He’s a NSW and Test player for a reason,” Farah told NRL.com.

“He will provide leadership both on and off the field. When the important games come along, he is a player Newcastle know they can rely on to play well.”

The betting monster that rugby league created has now come for its players

The Knights come up against Farah’s former club Wests Tigers in the Hunter this Sunday.

It is also doubles as Mitchell Pearce’s 300th NRL game.
