Villa were the lowest spenders in the Premier League over the summer market.
Konsa insists the PSR rules have held the club back, stating from England's training camp: "It is crazy. I don't understand it myself, but from the outside looking in, it doesn't look too good. I know that. I know it's really killed us this transfer window.
"We're going to have to deal with what we've got now.
"I definitely didn't watch that (transfer deadline day). It's been tough, especially for us.
"I knew that signing players was going to be difficult for us so I did not look at transfer deadline day.
"Around eight o'clock, I went on Villa's social media to see what happened. I saw that we signed three players, who are really good and have Premier League experience.
"I think that's what we needed as well."
Villa added Victor Lindelof, Jadon Sancho and Harvey Elliott to their ranks on deadline day, with their next Premier League match coming against Everton on Saturday, September 13th.
