Northampton Town were beaten 4-0 by Portsmouth at Fratton Park on a difficult evening on the South Coast for the Cobblers.

The away side missed a couple of chances in the first half, and fell behind to a John Marquis goal shortly before half-time.

Two goals in three minutes then saw the home side wrestle control, as Marquis grabbed a second before Ronan Curtis added a third.

Marcus Harness added a fourth late on, as Northampton suffered a heavy loss that means they now have the weakest goal difference in League One, and face two big games against Wigan and MK Dons in the next week.

After a few half-chances, Ryan Watson passed up a glorious chance to put Northampton in front when he evaded some covering defenders but fired wide.

Ricky Korboa and Watson would also have further chances they couldn’t take in the opening half, and Northampton would regret that as they fell behind in the final six minutes of normal time in the first half.

Marquis put Portsmouth ahead, with the in-form striker turning in the rebound after Jonathan Mitchell saved an initial strike.

The home side’s number 9 would continue to cause trouble for the away side, before Marquis made it 2-0 a few moments after half-time as the striker turned in the rebound when Curtis’ initial strike was saved.

It would then be 3-0 barely minutes later, as Curtis swept a strike into the back of the home net.

The fourth would come late on, as Harness headed in a cross to rubber-stamp victory for the hosts.
