The two sides, who meet in the Carling Cup third round, are separated by 68 league places but with Red boss Roy Hodgson fielding a team made up of fringe players and reserves - of whom Wilson is one - there is always the prospect of an upset.
However, the former Rangers defender, who along with goalkeeper Brad Jones will make his first-team debut, is determined not to let that happen as he believes Liverpool can go all the way in this competition.
"It would be fantastic to get to Wembley," said the 18-year-old.
"We have just got to take it one step at a time. There are no easy ties as cup football is a one-off.
"Sometimes it's tough playing against a team from a lower league because this is their cup final and they are out to impress, and you know they will put everything into the game.
"We won't take our foot off the gas as we know complacency can sometimes kick in."
Northampton beat Championship side Reading on penalties in the previous round and Wilson said that showed they should not be written off before kick-off.
"That shows you they have got great character in the team to keep going right to the end and we'll have to guard against that," he added.
"For any player Anfield is a massive stage to play at no matter whether you play a League Two side or one from the Champions League.
"They will be up for it and we have to make sure we play well and win the game."
Another youngster keen to make an impression will be England Under-19 captain Jonjo Shelvey, who is also hoping to make his first-team debut.
"Jonjo was excellent when I played alongside him for the reserves last week and if he's given a chance I think he is well worth it because he had a great game," said Wilson, a £2million signing from Rangers in the summer.
"Jonjo is a quality young player and if he is given a chance then I'm sure he wouldn't let anyone down.
"He signed at the same time as me and we get on really well. We have got some good lads here and I get on really well with them."
