They leapfrogged the Baggies, who slipped to 21st, just three points above the bottom three, having played a game more than all of the sides below them.

But as much as the hosts impressed in a busy performance, full of pace, movement and intent, West Brom were abysmal,

showing just why they had lost 10 in a row away from home before last week's last gasp draw against Derby County.

Chaplin could have made it 1-0 inside two minutes with a flicked effort that went wide at the near post, and he also went close with a drilled strike across goal before calmly slotting Pompey ahead from Ali's measured pass.

Ali's equally cool one-on-one finish rewarded continued attacking purpose and pressure, while Terry Devlin and Adrian Segecic also had chances to add to the advantage.

Adams did increase the advantage within four minutes of the restart, firing home from Chaplin's cushioned volley to as good as seal victory, and further demoralise a West Brom side who have now already lost 12 matches away from home this term.

Mikey Johnston did manage an attempt on target for the Baggies, their only one of the game,

when his curling long-range strike was well tipped over by Pompey keeper Nicholas Schmid.

But Portsmouth remained in full control, and could have easily added to their lead, with the only blemish and ankle injury suffered by Colby Bishop in the second half.

Ibu Adams had already endeared himself to the frat and faithful even before scoring in the South Coast derby.

And he continues to look an astute January signing for Pompey after capping another impressive display with his second goal in as many games.

The midfielder wrapped up a comfortable 3-0 victory over West Brom at Fratton Park, following earlier strikes from Connor Chaplin and Milenic Alli.

It was a dominant display from the hosts and Adams now wants the Blues to produce more confident showings.

He said, It's a massive win for us and the first thing that we need to remember is that we're a good team.

A performance like that is very much overdue and if we keep playing that way then I think we're going to be okay.

It's a massive win for us and the first thing that we need to remember is that we're a good team.

We didn't show any fear and it just shows that we can mix things up and have plenty of confidence, which is a massive thing in this game.

You could see it in the first half, while after the break it was just about making sure they didn't get one back.

I enjoyed myself out there and I'm sure the rest of the boys felt the same, but the big question is whether we can do that continuously.

Adams struck early in the second half, after being teed up by Connor Chaplin, with a finish that hit keeper Max O'Leary and looped into the net.
