Villa v Man City: Vlaar - Guzan in the form of his life
Vlaar has been thoroughly impressed with the quality of displays from Guzan this term and also in the previous campaign when he won both of the main Player of the Year awards.
Skipper Vlaar says Guzan offers the back four - and the rest of the team for that matter - masses of confidence.
He said: "He's in the form of his life. He showed that last season and he has started this season the same. He's absolutely great for us.
"He gives the back four confidence. And that's so important.
"But it's not just for the defenders, it's for the whole team. If you have a goalkeeper like that and he keeps on making great saves, that's terrific."
Vlaar says the team head into the match with Man City in great heart following the solid start to the season, although he accepts the exciting encounter is a big challenge.
The skipper wants a win to keep the momentum going following the top-flight win at Norwich and also to send the home fans happy.
He added: "We had a good win on Saturday and a big defeat on Tuesday. We now have a chance to get a nice result against a big team on Saturday.
"They have a great squad, great team and great players. It's a great challenge for us.
"Let's hope we get the home fans a good result too.
"It's a big job. It's a big challenge. But we look forward to it. Despite the result on Tuesday, we are in a good mood.
"We have to believe in ourselves. We do. The squad is strong and the spirit is good. We are all focused.
"We all want a win at home for ourselves, the fans and the club. It didn't happen yet.
"Newcastle wasn't our best game. It's small things - little things - that can make the difference. We have to try to make it better so we get a win."
