Australian league legends Brad Fittler and Darren Lockyer have chimed in with their opinions about Shaun Johnson's heroics in extra time, to seal a 20-16 win against the Panthers in last night's NRL match.

Today on the Channel Nine Sunday Footy Show former Roosters five-eighth Fittler criticised Johnson for not doing enough work taking the ball to the line.

"He (Johnson) needs to get his jersey dirty sometimes," said Fittler.

"I think sometimes he plays off the line a lot, if he comes off (the field) with a dirty jersey they would win a lot."

Former Broncos five-eighth Lockyer praised Johnson’s ability to read what was in front of him and secure the win for his side.
