MATCH PREVIEW
Ipswich have been a bogey side for Portsmouth, who have won only one of the last 17 league matches between these clubs and have failed to score in eight of their last 12 games against Town.
But Pompey make this trip to East Anglia in good form. They have won their last three league games without letting in a goal, going almost five-and-a-half hours of Championship football without conceding.
Ipswich have played more matches this season than any other team in the division. Their 2-0 defeat at leaders QPR - the Tractor Boys' 40th game of the campaign - was their first loss in seven league outings.
But their performances since the arrival of Paul Jewell have seen them transformed into possible play-off contenders. They were the better side for most of the first half on Tuesday, and are yet to lose at home since Jewell took over as manager.
