Nathan Cleary may be blaming himself for Penrith's NRL grand-final loss but his NSW teammates have backed him to bounce back in Origin I next Wednesday night.

The 22-year-old Panthers halfback was in tears in the sheds at ANZ Stadium after Sunday night's heartbreaking 26-20 loss to Melbourne.

Most crushing moment was his looping cut-out pass that was intercepted by Storm winger Suliasi Vunivalu who ran the length of the field to score.

And with a short turnaround to get his mind right it raised doubts Cleary could struggle to fire for the Blues.

However, NSW fullback James Tedesco said once Cleary gets into camp on the Central Coast on Wednesday night his mood will lift.

"100 per cent. He was (Penrith's) best player all year and it was disappointing how it went down, but he's a young kid and I'm sure he'll get into camp and get around the boys and be ready to go," Tedesco said.

"I haven't (spoken to him) but I really felt for him.

"He was obviously really disappointed but he was the best player all year for them and for the whole NRL.

"He shouldn't be too hard on himself but I think the way he developed and took Penrith to the grand final, he pretty much carried them there.

"He'll obviously be really disappointed but I'm keen to get him in and talk to him and catch up with him."

Five-eighth Luke Keary is pushing to make his Origin debut in Adelaide next Wednesday night alongside Cleary.

The Roosters star spent time in camp with the Blues in 2018 and got to know Cleary well enough to know he can recover from the disappointment quickly.

"He's a good kid and everyone sees the maturity from afar and he's very calm headed, he's very mature for his age so he'll bounce back," he said.
