The two sides met in the fourth round three years ago where an injury-time penalty from Jermaine Beckford forced a replay - which Spurs won 3-1 at Elland Road.
Leeds are having an inconsistent season in the Championship, lying 11th after 28 games, but Dawson has highlighted the quality of the Yorkshire side’s squad and the skills of manager Neil Warnock as reasons to be cautious ahead of the clash.
"Leeds is a great place to play football and I’m sure Elland Road will be rocking again on Sunday," Dawson told the club's official website.

"It’s a special stadium and being a Yorkshire lad myself, I’ll have a lot of friends and family there - it’s like a home game for them! It’s a massive football club and one that wants to be back in the Premier League.
"Neil Warnock always gets his teams right up for matches, it will be a sell-out, the fans will be right behind them and the atmosphere will be brilliant. We have to be ready, and I’m sure we will be.
"Leeds have some top players, they are doing well in the Championship and this is a one-off game. If we’re not at the races, we’ll come unstuck. We have to be professional, do the job and try to get through to the next round."
