Aston Villa: Ashley Young says players "hungrier" than ever
He said: "There are no nerves at all and we are not looking behind us. We are looking ahead.
"We have had a blip but everyone goes through those. With the strength of characters we have got here, I know we will be able to bounce back from that.
"People ask about Arsenal but we are not concentrating on Arsenal. Our main focus is first of all Sunday and then the next 10 games.
"We know Tottenham are a good side who can play open football and cause a lot of damage and we've got to be wary of that but our own form is also good."
Villa have managed only five wins in 14 league games at home - compared to 10 victories on their travels.
Young said: "If you asked everyone around the club, they can't put their finger why our home form is like it is.
"It has not been as good as when we've played away. The recent home game with Stoke felt like a defeat after we had been 2-0 up with a few minutes to go and looked so comfortable.
"But we are still fourth with 10 games to go and that is the most important thing. We are looking to change that home form around."
O'Neill is weighing up whether to recall left-back Wilfred Bouma who has been out of action for eight months since dislocating an ankle in the Intertoto Cup match with Odense BK in late July.
The Dutch international came through a reserve game in midweek with no ill effects and O'Neill is mulling over whether to give him another second string outing or whether to bring him back into the senior set-up for the Spurs clash.
Striker Emile Heskey is expected to be fit after his recent Achilles problem but midfielder Steve Sidwell is still ruled out with an ankle injury although he will resume training on Monday.
Midfielder Barry Bannan and third-choice keeper Stuart Taylor have both gone on a month's loan to Derby and Cardiff respectively.
