Keep It Mean To Keep It Clean
In recent years Wolves haven't been known for their defensive strength, but that all changed with the appointment of manager Glenn Hoddle.
The team that once didn't so much leak goals in The Premiership as surrender to a deluge now have one of the best defensive records in The Championship.
And its that new found solidity that Rob Edwards thinks may hold the key against United.
'If you look back over the last 10-15 games we haven't conceded all that many goals,' said Edwards.
'We conceded a couple against Reading and a couple against Coventry which was particularly disappointing.
'But we've also kept a fair few clean sheets and that has to be good news going in to face an attack like Manchester United's.'
Rob's place in the starting line up is by no means a foregone conclusion. But he is hoping that whoever makes a start, they continue stand firm as a unit, and not present the game to United on a plate
'Whoever is selected at the back, our aim has to be to try and get another clean sheet or at least make it as hard for United as we can.
'We must make sure we don't gift them anything and that if they do score they have had to earn it.'
The fans who inhabit Wolverhampton are never the easiest to please. Having known greatness in the past, there is a tangible desire within the Molineux faithful to see Wanderers take their place once again in the nations elite.
And their performance on Sunday could be just as important as the teams.
'I'm sure the fans will be up for it and it will be a great atmosphere right from the start.' said Rob
'We'll have to keep our concentration and keep things tight for the first spell because the last thing you want to do against a team like United is concede an early goal.'
No one is under any illusions regarding the size of the task Wolves are undertaking. But that doesn't mean Wolves will be playing with a stomach full of fear.
It's an opportunity to show what the team's really capable of, and its one Rob hopes Wolves can enjoy.
'Obviously it's a massive test but we're all really looking forward to it because it's a chance for us to see how we cope against one of the best teams in Europe.'
It's been nearly half a century since that was said of Stan Cullis' Wolverhampton Wanderers.
But on Sunday they have the best chance for a long time to prove they can still mix it with the greats.
