Leyton Orient will look to pull off a major upset this evening when they travel to Premier League Aston Villa in the second round of the Capital One Cup.
Paul Lambert's side have started the season with four points from two games and have yet to concede a goal.
But the O's may fancy their chances of a cup shock at Villa Park against a side that have struggled in the top flight and domestic cups in recent years.
Villa were dumped out of the FA Cup by League 1 outfit Sheffield United last season and the previous year were knocked out of the competition by Bradford and the FA Cup by Millwall.
Russell Slade also has history of knocking out a side managed by Lambert after the O's defeated Norwich City in the FA Cup three years ago.
The O's could bring former Aston Villa youngster Shane Lowry back into the defence for tonight's game and there is an outside chance Shaun Batt could be fit to make the squad.
Slade, whose side defeated Plymouth on penalties in the last round, said: "We might have to rotate the squad but this time around I've got a good group of 20. They will all get pitch time as the season progresses. We'll have to have a look at how we've come out of Saturday's game and look at the situation for Wednesday.
"It's a little bit of a problem because it's OK for Villa because they don't play until Sunday but we play on the Saturday so we get less recovery time.
"I'm sure Paul will make a few changes. He must be delighted with the start they have made."
