Jan Vertonghen admits Tottenham did not deserve to beat Burnley.
Spurs had gone a goal ahead through Nacer Chadli but were pegged back by a Sam Vokes equaliser and the game ended in a 1-1 draw.
It means a replay will be added to the club's already busy fixture schedule, but the Belgian defender admits Spurs can have few complaints.
He said after the game: "We played better in the second half but still it wasn't good enough. They tried to put us under pressure. We played better in the second half but still it wasn't good enough.
"We wanted to do the job here but hopefully we can go through at White Hart Lane."
Head coach Mauricio Pochettino similarly admitted the club struggled creatively, particularly in the first 45 minutes.
He told Spurs TV: The first half was difficult and poor. But the second half was a turnaround. We scored and the game was ours but you never give up and they got back in the game. I am disappointed because we have to play another game. We have a lot of games ahead."
Both teams had three shots on target, with Spurs having six total efforts to Burnley's five. With possession narrowly 52 per cent to 48 per cent in Tottenham's favour and each team winning four corners each, it really is hard to say convincingly that Spurs deserved anything more than a draw, and the players and head coach know it.
