Fratton Park is full to capacity for this afternoon's League One contest with Fleetwood (3pm kick-off).
The last few seats were snapped up on Saturday morning, with fans eager to see if Danny Cowley's side can make it four wins in a row.
There are a host of activities for young supporters attending the game, with the Junior Fanzone open behind the North Stand from 1pm.
There is 10 per cent of junior replica shirts in the club shop, while Piglet's Pantry will be selling a hot dog and Fanta or Sprite in the kiosks for just £6 for fans aged 12 and under.
Pompey are also in action at Fratton Park against Oxford on Tuesday night and then Accrington next Saturday. Tickets for both matches are available to buy online here.
