Manager John Mousinho feels his Portsmouth side are back on track after thrashing Northampton 4-1 at Fratton Park.

Paddy Lane scored twice as the leaders cruised to victory despite having debutant Tom McIntyre sent off.

Connor Ogilvie and Callum Lang also netted while Colby Bishop missed a penalty for Pompey, who had debutant Tom McIntyre sent off, before Marc Leonard grabbed a consolation for Northampton.

It is now 10 points from four games for Portsmouth since a 3-0 home defeat by Leyton Orient.

Mousinho said: “I am delighted with the performance and everything we did in the first hour.

“We came out the traps showing we meant business and were determined to cast out the demon of the Leyton Orient result. I think that has been hanging over us since then.

“We were good value for the 2-0 lead. We missed a penalty and I felt we could have had more in the first half.

“We started the second half a bit cagey and of course the sending off changed things.

“But we kept our heads and put the game to bed. They got a late goal and even with the added 10 minutes I felt we weren’t in any danger.

“My initial reaction to the sending off was that I thought it was a great tackle. In terms of appealing, we’ll look at it in detail and then decide.”

Pompey took the lead after seven minutes when Marlon Pack’s free-kick from 30 yards was headed home by Ogilvie.

The second came after 16 minutes. A long clearance from Pack found Lane, who turned inside a defender to drive home.

Pompey were awarded a penalty two minutes before half-time after Harvey Lintott pushed Myles Peart-Harris over but Bishop’s tame kick was easily saved by Lee Burge.

Pompey were reduced to 10 men after 54 minutes when McIntyre was shown a straight red for a foul on Mitchell Pinnock.

But Pompey got a third in the 58th minute, Lane playing a one-two before slotting home.

It was 4-0 after 71 minutes as an in-swinging free-kick from Pack saw Lang pick up the loose ball and stab it past Burge.

Northampton got a consolation goal a minute from time when Leonard fired into the roof of the net from a corner.

Cobblers boss Jon Brady said: “It is very disappointing.

“We’ve conceded an early goal from a set piece, which we should defend better. The goals we gave away were more down to us giving them to Portsmouth rather than them executing them well.

“They’re fighting to win the league and we’re fighting to stay in it. We’ve had some great form recently but the last two games have been too easy for the opposition.

“Just look at the team I have put out. It’s nowhere near the team I had picking up three points not long ago.

“am Hoskins has come off with his hamstring which is a blow. Sam Sherring has felt his ankle in the warm-up, so we were unable to get him on, and Ben Fox has been out all season, so could only get 15 minutes on the pitch.

“We started looking like we had purpose when they went down to 10 but then we got sucker-punched with their third a couple of minutes later.”

Manager John Mousinho hailed Portsmouth’s first-half showing against Barnsley as one of the best displays since he took charge after they clung on for a 3-2 win at Oakwell.

Colby Bishop, Paddy Lane and Connor Ogilvie all struck inside 16 minutes as the Blues made a dream start before second-half strikes from Barry Cotter and Callum Styles led to a tense finish.

However, Pompey held on for the win to go top of Sky Bet League One.

Asked if the first half was one of the best performances since he took over, Mousinho said: “It definitely was.

“We started on the front foot, we got the goals we deserved – the only thing that was lacking was the fourth or fifth goal that we definitely could have got.

“It’s one of the big areas of improvement for us to make sure we put games like this to bed because you saw second half that they come out, they make the changes and the whole game transforms.

“I thought we started to make poor decisions at certain moments.”

Mousinho’s side are now 19 games unbeaten in the league stretching back to March, a run which was preserved by Bishop’s stoppage-time equaliser at Derby on Saturday.

“I’m absolutely delighted – if you’d offered me four points from these two games I’d have snapped your hand off,” Mousinho added. “Being top is a bonus at this stage of the season.

“You saw the quality Barnsley have; they’ve won 7-0 here, they’ve won four on the spin without conceding and to do that to them, I’m really delighted.”

Pompey had already gone close twice when they were awarded an eighth-minute penalty.

Lane beat two players before feeding the ball to Gavin Whyte on the right and Bishop’s attempt to convert his low centre saw him fouled by Barnsley keeper Liam Roberts.

Bishop converted the spot-kick and 30 seconds later the visitors doubled their lead when the former Accrington striker’s flick-on found Lane and he calmly finished.

Ogilvie added the third when he headed home Joe Morrell’s cross from the right after 16 minutes.

Having failed to mount an attack of note before the break, Barnsley pulled one back just four minutes after the restart when half-time substitute Sam Cosgrove found Cotter, who drilled a low finish past Will Norris.

The hosts scored again with 13 minutes left when Norris fumbled Styles’ header and the ball trickled over the line.

Barnsley boss Neill Collins said: “I think I’d say that it’s important we don’t take anything out of proportion – I say that about both halves.

“The first goal really affected us because within a minute you’re 2-0 down.

“You can’t start a game like that but lots of positives and we went right to the very end; we could have been sitting here with a point.”

A blistering start helped Portsmouth secure a 3-2 win over Barnsley at Oakwell that sent them top of Sky Bet League One.

Colby Bishop, Paddy Lane and Connor Ogilvie gave the Blues a dream start before second-half strikes from Barry Cotter and Callum Styles led to a tense finish.

Gavin Whyte had already seen a first-minute effort deflected wide and Bishop had headed over the bar before Pompey were awarded an eighth-minute penalty.

Lane beat two players before feeding the ball to Northern Ireland winger Whyte on the right and Bishop’s attempt to convert his low centre saw him fouled by Barnsley keeper Liam Roberts.
