Spurs face Villa today.
"When it came to it, Villa were doing a bit of a revamp and there was a very good offer on the table to come down to Tottenham. That's how it was," Friedel told Villa's website.
"I never once pushed for it and never would I either. I would never disrespect the club in that manner.
"I left on incredibly amicable terms. I did my best for the club every single day - whether in games or in training. I gave my all for the club."
