The USA international has just ended a successful loan stint at Hull City.
Guzan, 26, will follow their fortunes from afar, with a view from the Villa bench the best he can hope for.
He said: "I'm sad to be going. I've enjoyed my football.
"Hull City gave me an opportunity and I have played the most consistent football since I have been in England. It was a great few months. I will definitely check the scoresheet now to see how they do every week.
"I haven't talked with Villa yet. We will see what happens in the next few weeks.
"Whether I am part of their plans or not I'm not quite sure.
"Hopefully they will have taken notice. If not, I guess my answer is that I won't want to stay."
