After netting just once in their opening three matches, the Blues have made profound improvements in the final third.
Kenny Jackett’s side's 3-1 victory at Lincoln took their tally to 19 goals from 11 games in League One this season.
There have been impressive attacking displays in victories over Burton Albion (4-2), Sunderland (3-1), Northampton (4-0) and most recently the Imps.
Certainly, Pompey have an embarrassment of riches when it comes to their forward players.
John Marquis already has nine goals in all competitions and he's well supporterd by Marcus Harness, Ryan Williams, Ronan Curtis, Michael Jacobs, Ellis Harrison and Jordy Hiwula.
Given the sheer prowess, the Blues are strong contenders to score the most team goals in the third tier this season.
