Portsmouth lost 1-0 to AFC Wimbledon in League One at the weekend, as Kenny Jackett becomes increasingly under-fire at Fratton Park.

Thomas Terell’s 93rd-minute goal gave Wimbledon a fourth-straight win against Portsmouth on Saturday.

The win took them to 21st in League One, and sunk Portsmouth to 18th - just one point separating the two.

In what was meant to be Pompey’s season, Jackett has guided his side to a dismal start to the season, and his job is seemingly hanging by a thread with each passing match.

Having recruited well in the summer, fans were expecting Jackett to build on a 4th-place finish last season, where they also lifted the EFL Trophy.

But that’s been far from the case at Fratton Park and right now, the threat of relegation is a more pressing issue for Portsmouth than achieving promotion to the Championship.

Jackett needs results fast or he could well become the latest victim of the sack race, and Saturday's defeat at Wimbledon will give him plenty to ponder before tomorrow's game against Lincoln.

Here we take a look at three things we’ve learned about Pompey from the Wimbledon defeat:

Boring, Boring Portsmouth

A common theme arising from the Wimbledon defeat was that Jackett’s team are playing the most boring football that they’ve played in his three-year tenure.

Last season they were arguably the most entertaining club in League One, and were unlucky to miss out on automatic promotion before crashing out of the play-offs.

Pompey fans have become acquired with a more enticing style of football in their rise back up the Football League, but have been starved of that this season.

Poor travellers

The defeat was Portsmouth’s fourth of the season, and their fourth away from home.

They've picked up just four points from six away games in League One this season, and after a win at Doncaster and a win at Oxford in the EFL Cup this month, the trip to Wimbledon was expected to be rather routine.

But Pompey’s short-lived momentum came to a halt and the same old problems have risen again.

Set-pieces vulnerability

Terell’s late winner at the weekend came from a free-kick on the flank, which he headed past Craig MacGillivray in the Portsmouth goal.

Although Portsmouth haven’t had the worst defence in League One this season (11 goals conceded in 12 games), they have developed an unwanted knack for conceding from set-pieces.

Having conceded a late equaliser against Oxford before beating them on penalties earlier month, the issue of set-pieces will need to be addressed by Jackett before his side host Lincoln tomorrow night.
