The former Leeds man has had his first-team chances limited since being signed by former Villa boss Martin O'Neill in 2009.
Injuries and loss of form have marred the ?6million move but, after completing 90 minutes against Fulham last weekend, Delph has renewed optimism.
"I am chuffed with starting the first game and hopefully I can do well for this gaffer," the 20-year-old told the Daily Mirror.
"It was my first 90 minutes in a long time and hopefully, with the new manager, the people around him and the players around me, I can improve.
"It is very good for me personally, because I haven't been in favour much in my Villa career so far.
"There is a lot to work to do for myself personally. I pinged a few good passes at Fulham, but I also shanked a few as well."
Meanwhile, new signing Shay Given, 35, is struggling to be fit to face his former club Blackburn on Saturday.
The goalkeeper picked up a groin strain in the 0-0 draw at Craven Cottage, and Delph admits he is fast becoming a crucial member of the squad.
"He is a really strong character," said Delph. "For the whole team and the back four he has been unbelievable.
"As long as we can keep him in there, I think we will do really well this season."
