Kenny Jackett saluted a superb performance that kept the Pompey bandwagon rolling.
A comfortable 3-0 victory over Plymouth at Fratton Park continued their unbeaten start to the League One campaign.
Only Peterborough’s superior goal difference is keeping Pompey off the top of the table after six fixtures.
Ronan Curtis’ brace and a Jamal Lowe strike did the damage against Argyle and Jackett was delighted with the display.
The Blues boss said: “We played very well and deserved to win. In the first 25-30 minutes we were absolutely excellent.
“A few injuries stopped us a bit, but we sorted ourselves out at the break, the substitutes came on and we went on to produce a comprehensive performance.
"We played very and deserved to win. In the first 25-30 minutes we were absolutely excellent."
“We lost three players in the first half and yet I felt the ones coming on are as good as the ones that came off.
“The second goal was a really key one and from that point we were able to go on and win the game in style.”
Oli Hawkins went off late in the first half, while Anton Walkes and Jack Whatmough failed to emerge after the interval.
Jackett explained: “Oli’s struggled with his back at times and he felt it was tracing down his leg, which was slightly frustrating, but it doesn’t look too bad.
“Anton felt his groin after about 20 minutes of the game, while it was similar for Jack with his hamstring.
“Neither of them were too bad, but it looked like the guys on the right side of our defence were labouring slightly towards the break.
“Christian Burgess and Nathan Thompson came on and that helped us deal with their attacking players.
“We’ll see how they are, but injuries are going to happen at stages of the season and if you want to be successful, you need to use your squad.”
