Paul Gallen will end his short-lived representative retirement to captain NSW City against Country, however, he also left the door open for a possible Blues comeback.

"That's up to Laurie if I'm required. All I can do is go out and play good for my club," Gallen said on Thursday.

"I'm happy with my club form at the moment so I'm not too sure."

Asked if he would say no to Daley, Gallen said: "You'd never say no to Laurie Daley, same as I didn't say no to Brad Fittler when he rang me and asked me.

"But I'm not going to go there yet."

Daley praised Gallen's performances since announcing his intention to retire from rep football, but was also cagey on the chances of him seeking out his former skipper for one last hurrah.

Daley pointed to Gallen's 11 Dally M points so far this year - second behind Cameron Smith.

"I think Gal's a wonderful player and he's playing really well at the moment. Who knows what's around the corner," Daley said.

"Look, he made himself unavailable. I haven't spoken to him since, but things can change pretty quickly in rugby league, as we know.

"At this stage, Gal's looking forward to playing for City and we'll see what happens after that."

At 35 years of age, Gallen is the oldest active player in the NRL but believes he is still playing at Origin level for the Sharks.

After eight rounds, he is No.1 in hit-ups (144) and third in metres gained (1480).

Gallen has revealed Fittler asked in early March about making just his second appearance in the City-Country fixture, but only followed him up on Tuesday.

"I never heard from him last week, and I didn't hear from him till two days ago," he said.

"I thought that he'd forgotten about it, but obviously he give me a call and when Brad Fittler asks you to do something, I'm not one to say no.

“I feel honoured to be captaining the City side in the last ever Country-City match.”

“This fixture allows players on the cusp of an Origin call-up the chance to perform on the big stage and push their claim for a spot in Laurie Daley’s NSW side.

“Having lost my only game for City, I’d love to lead the side to victory. There will be a number of potential Origin candidates whom I hope to pass on my experience and knowledge to.”
