Villa meet Southampton today.
"When you lose six games on the bounce, it's extremely frustrating," said Guzan to the Birmingham Mail.
"I'd be lying if I said it didn't affect me, but that's when you need big characters and guys to step up and say, 'right okay, I'm going to do everything in my power to get things right'.
"Sometimes you need more than that.
"There are no easy games in this league, I've always said that.
"Going on that run of six defeats was tough because it becomes more and more challenging to stop it.
"For us the point at West Ham was massive and we need to build on that.
"From top to bottom we have not been at our best.
"We were not very sharp but in terms of being in the dressing room, sometimes you have to let your voice be heard.
"You need guys to step up and sort the issue at hand out."
