Holt has spent the second half of the season on loan at Villa Park from Wigan Athletic and is loving his time back in the Premier League, even though he has only played a limited role.
Wigan could join Villa in the top flight next season after securing a Championship play-off berth, and Holt accepts that any decision on his future will be made by his parent club.
The 33-year-old has a contract with the Latics until 2016 and will report back after Villa's final three games, but for the moment he is concentrating on making an impact in the next couple of weeks.
Speaking about perhaps staying longer at Villa, Holt said in the Birmingham Mail: "It's not a conversation I've had with him (Lambert).
"I didn't have it last week and I won't have it this week. It's up to me, in the games left, to play the way I am.
"I'm a Wigan player and contracted for two years and whatever happens between now and then we'll see.
"It's nice to be back and involved in the Premier League. The difference is massive. I've been itching for a few weeks. I've been working hard and training hard.
"You have to keep on top of it. It's harder when you're not playing because you're not getting the minutes and you've got to keep working harder.
"I've been in good shape and I've just been waiting for my chance."
