Guzan overtook Shay Given as the club’s first-choice stopper earlier in the season after being understudy throughout his previous seasons at the club.
And he is hoping to continue to develop and hold on to his place in Villa boss Paul Lambert’s starting line-up.

"Every day there is room to improve. You look at a guy like Brad Friedel. He would probably say the same that he continues to try and get better.
"Goalkeepers tend to peak at a later part in your career. Hopefully I can keep this up and continue to be called upon. If that happens then I want to do a job."
The 28-year-old believes he is making the most of the chance to establish himself this season, and is desperate to help his side in their battle to stay in the Premier League.
He added: "When you play consistent football you give yourself the chance and opportunity to get better and prove what you can bring to the table. Everyone needs a chance and opportunity.
"Fortunately for me I was given that chance and opportunity earlier in the season and when you are, you have to take it.
"For me I continue to try to prove week in week out to justify the selection and try to improve to help the team and yourself.
"It is about continual learning to get better. You can't get complacent with where you are at because there is always someone creeping up behind you."
Next up for Villa is a home clash against Liverpool in the Premier League on Saturday.
