Gary Roberts believes Pompey’s League Two rivals have their work cut out with the fire-power Paul Cook has at his disposal.
They are the joint-second-highest scorers in the division – behind leaders Plymouth (28).
Since August, only Accrington have stopped Pompey from scoring.
Kyle Bennett has targeted 12 goals for the campaign, Carl Baker sits on six strikes, while Conor Chaplin has five under his belt already.
Roberts himself has seven in the league.
The victory against Mansfield saw Pompey score four times at home for the second time this season, after beating Wycombe 4-2 in September.
And Roberts knows with the attacking quality in the squad, opposition defences should be fearful.
He said: ‘You look at the front four who played Saturday – you have myself, Benno, who is a terrific player, and Carl Baker, who has scored tons of goals throughout his career, Conor Chaplin, who is deadly, and even the lads coming on.
‘You look at the forward players. We have got some fire-power.
‘We have been quite strong at the back. If we can keep that up, the way the lads have been defending in the league in the past couple of games, then you know we are going to get goals.
‘There’s goals throughout the team.
‘Even when Danny Rose pops up from midfield.
‘We shouldn’t really get clean sheets kept against us with that fire-power, so we have got some good players.
‘We are strong at the top end of the pitch.’
