Rochdale continued to play with style and Henderson opened the scoring in the 45th minute when Andrew Cannon played a risky ball onto the box and the skipper fired first-time into the corner.
Pochettino could rest a number of players for the game against Rochdale while the Spurs manager will take a late decision on Kane who is battling a sprained ankle.
During and after the game, Spurs fans took to Twitter to hail Moura's display, suggesting that he was the best player on the park and one of the few players to come out of the game with any credit, even adding that he has already repaid his transfer fee more than Fernando Llorente has.
"It's unbelievable", said Henderson.
"We can't wait to go to Wembley".
The Brazilian wide man arrived from Paris Saint-Germain on deadline day and has been waiting for his first start, with Pochettino unleashing him against Rochdale to great effect - though his side couldn't grab the win.
Somebody showed the Tottenham manager a picture of the Rochdale pitch.
"We have another opportunity at Wembley, the same situation like before".
"I was not surprised".
"This is a different game, a different competition and it will be tough. We took the opposition on and we know how good they are", Hill, who nearly lost his flat cap in the delirious scenes following Davies's equaliser, said.
Romelu Lukaku scored twice for United as they won 2-0 in a match where Jose Mourinho's side had to make do without Paul Pogba after the midfielder withdrew on the morning of the match with an unspecified "illness".
"It could have been football suicide but for us to score the goal and go in 1-0 at half-time was tremendous, a marvellous feeling for those players".
"I was conscious about the FA Cup, the football and the image that we are going to sell, but the care for the players, too". "If they find a way in the VAR that the VAR is always right and always bring the truth, I'm happy".
