Liverpool have supplied Marine with video analysis of Tottenham Hotspur ahead of their FA Cup third round tie on Sunday.
Jose Mourinho and his side visit eighth-tier Marine knowing defeat would be the greatest upset in the history of the competition.
And Liverpool helped their neighbours obtain scouting knowledge by offering match footage from the current campaign.
Marine manager Neil Young told the ECHO : "You have to do your due diligence, don't you?
"We've watched a lot of games of Tottenham, and had some help off Liverpool to be fair in terms of help to access to the games.
"We don't have those facilities and they have been very good to us to help us get access to those games.
"So we've looked at Tottenham in the Europa League, in the League Cup and in the Premier League and we have an idea of a way to play the game which might not happen.
"We have to be organised and I have to set the lads up in a way which I believe will give us the best chance to negate Tottenham.
"Leeds United haven't been able to do it in the last week, Brentford couldn't do it in the League Cup. All I can do is prepare us as best we can and I know when I put the lads out on that pitch they will give absolutely everything they've got.
"That is all you can ask for."
Marine also confirmed Everton offered their support alongside their neighbours this week.
They tweeted: "When our training facilities were cancelled for tonight's and Saturday’s sessions and all centres and schools closed, Everton and Liverpool offered their facilities for us to use within 30 minutes."
