Stoke will seek to halt their slide down the Championship table when Portsmouth visit on Saturday (15:00 GMT).
The Potters occupied the second automatic promotion place in late November but have slipped down to 17th, picking up just three wins in their past 18 games.
The four sides immediately above them remain within three points, however.
Portsmouth's survival was ensured on Tuesday night, despite a 5-1 defeat at Coventry, as Oxford's defeat to Wrexham left the Blues safe with two games remaining.
Stoke City have won four of their past five league meetings with Portsmouth (L1), just one fewer than their previous 20 prior (W5 D8 L7).
Portsmouth are winless in seven league visits to Stoke (D2 L5) since a 2-0 triumph in February 1995 under Terry Fenwick.
Stoke have only won their final home league game in two of the past nine seasons (D2 L5), beating Brentford 1-0 in 2019-20 and Bristol City 4-0 in 2023-24.
Portsmouth have only won their final away game in one of their past eight second tier seasons (D2 L5), beating Bradford City 5-0 in 2002-03.
Stoke have lost their past two Championship matches; only once this season have they lost three on the spin, doing so from November to December.
