Leicester hooker Tom Youngs is still keeping his focus on the English shirt despite an injury to his back.
The English international's injury prevented the hooker from being considered for selection to tour Australia in the three-Test that England won 3-0.
"You always have to keep the goal there to get back in the England side. I don't think you can ever lose sight of it," he told the BBC.
"Because I was injured, yes you do end up doubting yourself a little. But you soon dust yourself down, get back here, train again and then you are ticking along again.
"I've always had determination, but there is probably a bit more there now to prove people wrong and prove to myself that I'm good enough."
Youngs isn't worried about not being called upon by England coach Eddie Jones as he says he just needs to work hard either way.
"It's never great not being selected, but there is no point moping about because you need to be training hard. I'm not one to mope, I just say 'fair enough, I understand' and then go off and work on things I need to work on," Youngs said.
"The back injury was probably the worst thing, because I couldn't prove anything.
"If I get the phone call great, but I'll concentrate on getting fit, playing and leading by example for the club.
