Blues run riot on the south coast
Town made it seven points from three games with a commanding victory away at Portsmouth.
Macauley Bonne opened the scoring late in the half before second-half strikes from Conor Chaplin, Sone Aluko and Wes Burns sealed the points.
Paul Cook made four changes to the side who travelled to Cambridge on Saturday with Christian Walton, Toto Nsiala, Lee Evans and Kyle Edwards all returning to the starting XI.
The first chance of the game went the way of Town after Edwards was scythed down on the left wing. Evans' low delivery from the resulting free-kick was only cleared as far as Chaplin, who saw his snapshot blocked behind for a corner at the near post.
Portsmouth had a good chance to take the lead on 15 minutes. Lee Brown raced onto Marcus Harness' flick-on before retuning the favour with a low ball into the box but the latter sidefooted wide of the mark.
A fiery game ensued in front of two sets of vocal fans at Fratton Park, Ronan Curtis and Marcus Harness picking up yellow cards for poor and late challenges on Janoi Donacien and Sam Morsy respectively.
Town took the lead just before the break in bizarre fashion. Bonne closed down and tackled Gavin Bazunu following a pass back to the Portsmouth 'keeper. The Blues forward kept his composure to bring the ball in from the touchline and rocket it into the top corner of the goal.
The Blues came out with intent at the beginning of the second half and doubled their advantage just eight minutes after the restart. Town worked the ball out to Donacien who played a pinpoint low ball across the box which Chaplin perfectly guided into the bottom corner.
And it was 3-0 just five minutes later. The attack began with Evans reading and brilliantly intercepting a pass midway inside Pompey's half. Chaplin retrieved the ball before passing the ball right to Aluko, whose right-footed effort squirmed under Bazuni in front of the travelling Blue Army.
The visitors continued to look the more likely as George Edmundson's volley was deflected behind following another dangerous Evans free-kick, substitute Burns seeing an effort saved at the near post shortly afterwards.
Burns wasn't to be denied moments later, tucking into the back of the net from another Donacien cross from the right wing to make it 4-0.
Walton had to be aware to parry away an effort from Reeco Hackett at the end of a rare venture for the hosts, Bonne seeing an effort blocked at the end of a Town counter from the resulting corner.
Pompey saw a bit more of the ball late on but without threatening in a totally dominant display from the Blues.
