Pompey will look to continue their unbeaten start to the season when Cheltenham visit Fratton Park on Saturday (3pm kick-off).
Their opponents are at the opposite end of the form table, having yet to collect a point – or even score a goal – so far.
After narrowly losing at Shrewsbury on the opening day, they suffered a 3-0 home reverese to Bolton and were then defeated 1-0 at Reading earlier in the week.
Birmingham also won 2-0 at Whaddon Road to ensure Carabao Cup hopes were snuffed out straight away.
It comes after Wade Elliott guided the Robins to a 16th-placed finish in League One last term – the second highest in the club’s history.
He had replaced Michael Duff in the hot-seat after the man who guided Cheltenham to the fourth tier crown in 2020/21 left for Barnsley.
Pompey have yet to lose to the Gloucestershire outfit at Fratton Park, winning two and drawing three of the five previous meetings.
They romped to a 4-0 success back in February, while fans will likely recall the 6-1 rout in 2017 that dramatically secured the League Two title.
Josh Dockerill (knee) and Tom Lowery (knee) are both sidelined, with Paddy Lane in contention to make his first appearance of the season after returning from an ankle knock.
Cheltenham midfielder Oli Hammond has gone for a scan after picking up an injury at Reading earlier in the week.
They could give a debut to wing-back Luciano D’Auria-Henry, who has just joined on a season-long loan from Fulham.
