Fulham manager Rene Meulensteen felt his team lacked quality in Sunday's 1-1 FA Cup fourth-round draw at Sheffield United.
Meulensteen's men appeared set for defeat to the League One side when Chris Porter put the hosts ahead just after the half-hour mark on Sunday.
However, United were reduced to 10 men early in the second half as Michael Doyle was dismissed following an off-the-ball altercation with Chris David.
Fulham took advantage of their numerical superiority and levelled matters through Hugo Rodallega, but could not complete the turnaround.
And Meulensteen accepted that his side did not do enough to avoid a replay that adds another game to the London club's already-crowded fixture schedule.
"They (Sheffield United) gave it their all and got their noses in front," the Dutchman said.
"We didn't produce enough quality to get the second goal. If there are positives to take out of the game it is that we are still in FA Cup and the young players did well.
"We're at Swansea on Tuesday. It's like an extended Christmas period - it just keeps on going."
