Wrexham meet Brighton again tomorrow week after holding the Championship club 1-1 on the south coast on Saturday.
Player-manager Andy Morrell: “It’s a great draw and the ideal carrot to hang in front of the lads in terms of trying to win the replay.
“But I’m trying hard not to get carried away because, not only do we have to beat a very good side in Brighton, we also have two or three very tough league matches ahead of us this month.
“First and foremost I want to keep the players focused on those matches.
“But, from the club’s point of view, the potential financial rewards of a game with Newcastle are there for all to see.
“I also lived in Newcastle for three or four years and watched them a fair few times, so it’s a good draw for me personally as well as the club.”
