The 24-year-old joined Villa as part of the deal that took James Milner to Manchester City before the transfer window closed.
However, Ireland is yet to show any of the goalscoring exploits he demonstrated during his time at the City of Manchester Stadium.
Ireland and Villa produced a disappointing display at the weekend when Bolton came from a goal down to claim a 1-1 draw.
The Republic of Ireland midfielder knows he is performing below par and believes he will be producing his best in the coming months.
"Of course, I'm still getting to understand the players out there on the pitch, still finding my feet," said Ireland.
"I pulled my hamstring, but I'm getting there. I hope by Christmas everything will be good."
Villa have a new manager in the shape of Gerard Houllier and Ireland is hoping the Frenchman can get the best out of his potential.
"I don't know much about how he deals with things as a manager," he added. "Hopefully he can get the best out of me."
