Pompey are now unbeaten from their opening nine league games this season.
In doing so, they equal a post-war feat achieved four times previously – but short of the 1948-49 record of 13.
The 2002-03 Division One title campaign was one of those instances.
Here’s a look back at the streak which happened under Harry Redknapp’s guidance...
Pompey 2 Nottingham Forest 0
Harry Redknapp handed debuts to seven players for the first match of the season, with Deon Burton and Vincent Pericard scoring before half-time to claim the victory.
Sheffield Utd 1 Pompey 1
Burton maintained his scoring run by netting a first-half equaliser to cancel out Peter Ndlovu’s opener for the Blades.
Palace 2 Pompey 3
Inspired half-time substitutions saw the Blues fight back from 2-0 down to claim victory.
Jason Crowe was among two players introduced from the bench at the interval and the right-back responded with two goals, Hayden Foxe grabbing the other.
Pompey 3 Watford 0
A return of three goals in seven minutes either side of half-time gave the hosts a comprehensive victory over the Hornets.
Paul Merson’s penalty, followed by goals from Svetoslav Todorov and Burton settled the occasion.
Grimsby 0 Pompey 1
Substitute Mark Burchill volleyed home an 85th-minute winner to claim a dramatic victory at Blundell Park.
Pompey 4 Brighton 2
Despite Matt Taylor’s early opener, Pompey slipped behind 2-1 against Brighton.
But Merson’s penalty, Todorov and Crowe completed the fightback to maintain their top-of-the-table placing.
Gillingham 1 Pompey 3
Merson, Burchill and substitute Gary O’Neil registered for dominant Pompey, with Kevin Jones pulling back a consolation on 70 minutes for the home side.
Pompey 1 Millwall 0
The Blues made it seven wins and a draw from their opening eight games.
Todorov was the match winner, converting Nigel Quashie’s pass, before later limping off with a knee injury.
Pompey 4 Wimbledon 1
Neil Shipperley had cancelled out Pericard’s opener before Redknapp’s men galloped away.
Todorov, Mark Williams’ own goal and Taylor completed the emphatic scoreline.
