Leicester City can ill afford to dwell on their latest defeat in their stuttered bid for promotion, says defender Ricardo Pereira.
The Foxes were beaten by relegation-threatened Millwall on Tuesday, but remained top of the table by virtue of Leeds' failure to beat Sunderland.
Ipswich can move above Leicester on Wednesday if they beat Watford.
"We cannot be too disappointed because we have a game in three days and we need to bounce back," Pereira said.
"We need to continue and focus, and if we do our job we will be fine."
Ryan Longman's stunning strike from the edge of the area that found the far corner of the net in the second half was the decisive moment on Tuesday's tense game at the Den.
