Cast your minds back to September when the Robins and Pompey drew level.
Today's game at Fratton Park will be only the second ever competitive meeting between Cheltenham and Portsmouth.
The first came earlier this season at the Abbey Business Stadium in what was an enthralling 2-2 draw. Jermaine McGlashan was the hero of that day after his stoppage time equaliser sealed a point for the Robins.
Patrick Agyemang had handed Portsmouth the lead in just the 5th minute but Jermaine McGlashan had levelled the scores just half an hour later. Once again Pompey took the lead, this time through Johnny Ertl right before half time but the Robins had deserved to win the game and their wing wizard provided a leveller moments before the full time whistle was due to blow.
