Sutton find themselves eight points clear of their opponents, with a win potentially putting them top for Christmas Day, writes Tom Feaheny.
"It will be a fantastic game, they are in good form, we look forward to the match, we are facing the team who I think will win the title," Doswell told SUFCTV.
"There should be a good crowd here and these are the kind of games, you look forward to, facing a side who have that aim to be going up."
Their preparation was helped with them avoiding a replay at Truro City due to a late winner that ensured they would be in the draw for the next round.
"It is such a relief to get through because the replay would have had an impact on our preparation in the league game,"
"Truro played well and were tough to break down, it was a tough game for us, other teams around us have exited the competition at this stage."
