Delph believes he is now showing his best form at Villa after admitting the start to his Villa career following his arrival from Leeds in 2009 was "dreadful".
"Probably the worst injury you can get in football is your anterior cruciate ligament. I also did my lateral meniscus and my medial as well.
"It's been a tough road but Alan Smith, the physio, has been with me side by side ever since.
''I've had great fitness coaches that have helped me in the past. I've just picked up little bits from everybody and managed to find the right balance.
"I train every day. I haven't missed a day's training since the gaffer's been here, unless I've been ill. To get over the injuries, basically it's just pure graft and pure hard work, starting at 9am, finishing at 3pm."
