The 32-year-oldâs loan spell at Villa Park reunites him with Paul Lambert, under whom he thrived when the pair were at Norwich, and Holt hopes he can repay his manager's faith in him.
"Obviously everyone has noticed I haven't been playing that much at Wigan," he told AVTV.
"It has been a frustrating year because I went to Wigan and got an injury and that has been hampering me a little bit.
"It is a massive opportunity for me, as I was in the Championship last week sitting on the bench.
"The way the last five months have gone have summed up my career to a T and how bizarre it has been: going back to the Championship and then coming back to the Premier League is just the way my career has gone and I've been very lucky.
"I see it as another chapter for me to step on again. I am sure the career I've had with the ups and downs has given me belief.
"Now it is up to me to show everyone I can get back that success I had with Norwich last season and bring it to Villa.
"I am sure with the players he (Lambert) has here it can only enhance me as a person and a player."
"I know what he expects and I am looking forward to working with him,â he added.
"He has spoken to me at length and I will try to do exactly what I can for this club.
"We all know it is a team in transition. The side are young but they have held their own.
"Hopefully I can bring something different, bring some experience to help them along and help them on the pitch as well."
