The striker is on loan at Coventry and out of contract at Villa Park in June but is yet to hear anything from the club.
“I knew the situation when I went back (after his Blackpool loan ended in January). I would have loved to have the opportunity to prove I could play,” Delfouneso told the Express & Star.
“Over the years a lot of players have come through and people might have questioned what I was doing and my attitude. That’s never been the case I have always looked to do my best in everything I do.
“I’m not going to put blame on anyone but they will have their say and I’ll have mine. I loved my time at Villa.
“When I came through a lot was said about me and I would have loved to do that with Villa. In the end I didn’t get the opportunity which would have helped me case.”
