Bannan has played just three times for the Eagles this season and only once - in a Capital One Cup defeat to Newcastle - since new boss Neil Warnock took over at Selhurst Park last month.
He said: "You've got to look at guys like Alan Hutton; in the past he wasn't playing for his club and was coming away and playing really well [for Scotland].
"The only thing I can do, when I come here, is do my all in training to get into the team.
"I keep myself fit. It's a shame I'm not playing but hopefully playing well here will impress the gaffer and I'll get the chance.
"I think [Neil Warnock] had just got the job the week I was coming away for the game against Germany.
"You obviously think if you're playing against Germany and doing well then you'll have a chance when you go back.
"But Palace were doing well at the time and it's just a case of waiting for your chance and taking it when you get in there."
