The Poland international penned a new deal with Villa a fortnight ago.
"I had two offers from different clubs in the summer but I never really focused on that," Cash told ESPN.
"My main priority is to stay at Villa. I think Villa's a great club, I've done a lot of work there obviously over the years to progress as a player and I still think there's a lot more to go to be honest.
"So my main priority I said in the summer to the manager when we had a chat that I wanted to stay, I wanted to keep improving and this year I think I found a good little bit of form and delighted that they came to me and offered me a deal.
"We always have an end of season talk and he just asked me where I was at and how I was feeling and that he'd love to keep me.
"I still had a few years left on my contract as well but it was a point where 'was I going to renew or what was the case?'
"I had an open and honest chat that I really want to stay. It's a great club. I feel really settled here. I feel at home here.
"I've got my house and stuff here and I just wanted to commit my future and then they came to me and offered me a new contract.
"It had been in the pipeline for a few months when we had the conversation. But I was never really set on leaving. I feel at home and feel settled.
"I have a good connection with the manager. We have a lot of conversations, not regularly, but we have conversations one-to-one a lot and he's a massive part in me obviously committing and obviously the club as well.
"It speaks for itself. Obviously playing for such a big club is an honour but having a manager that's so good behind it is definitely a big key factor."
