Lucas suggests both sides signing new players shows their similarities.
Both sides have picked up seven points from their opening four games and have struggled for goals while opening up the season with three clean sheets before their first loss of the campaign on their fourth outing.
Lucas said: "The two teams arrive in a similar situation with a lot of new players, a lot of new signings, and I think it's going to be a good game.
"We just have to approach it in the right way, as we did against Arsenal, and hopefully we get a good result there."
For some reason there seems to be a lot of onus on a game that is only the fifth of the league season. Of course it is an opportunity for a side to land an early-season blow on one of their fierce rivals but it is far from the be all and end all.
Liverpool made a series of signings of the summer that they are still integrating into the side, and United are doing their fair share of bedding in new players, and may be introducing another player this weekend in Anthony Martial.
So in the context Lucas is talking about he is absolutely spot on, there are a lot of similarities between two sides. The Brazilian has added that even at this stage it is still one of the biggest games of the season with the two most successful clubs in the country going head-to-head.
"I think if you get a good result there it can give you a lot of belief and confidence going forward.
"It's a team that will be challenging for the top four and titles so it's a good opportunity for us to put the result against West Ham behind us and start again."
Regardless of the respective targets the two sides may have this season, the fixture itself should be enough motivation for them to try and go out and win the game.
A win for either side could be a big early season blow, and used as a springboard for a decent run in the early stages of the season. After the defeats prior to the international break, and a lot of opinion suggesting that neither side can really afford to lose this early on, it will be interesting to see just how this game pans out.
