Luke Chambers and Josh Magennis spoilt Portsmouth’s Sky Bet League One promotion party as Wigan beat the newly-crowned champions 2-1 at Fratton Park.

Pompey almost took the lead after six minutes when a poor backpass was intercepted by Colby Bishop, who tried to chip stranded goalkeeper Sam Tickle but put it well wide.

Wigan’s Jonny Smith hit a post in the 13th minute, but the visitors took the lead 10 minutes later when Chambers put the loose ball past Pompey goalkeeper Will Norris.

Latics should have gone two-up just before half-time as Norris parried Charlie Kelman’s powerful shot but Chambers put the follow-up wide.

Despite half-time substitutions, Pompey struggled to claw their way back into the game and Wigan looked to have sealed the win when Magennis beat Norris with seven minutes to go.

Kusini Yengi pulled one back for Pompey, but despite piling on the pressure in stoppage time they could not secure a 28th victory of the season.

Charlton extended their unbeaten run to 12 games as they celebrated their longest streak in nearly 13 years with a 2-2 League One draw against Wigan.

In the 20th minute, Alfie May pressed for an opener and he caused Wigan captain Charlie Hughes to slice a clearance up and over goalkeeper Sam Tickle and into his own net.

Wigan had been second best but turned the game on its head just after the hour mark. First – in the 62nd minute – Charlie Kelman touched home to equalise after on-loan Fulham winger Martial Godo’s deflected shot fell his way.

Four minutes later, Kelman completed his brace via a close-range shot which deflected off Macaulay Gillesphey.

But 11 minutes from time, Charlton hit back through substitute Chuks Aneke, who headed home from a George Dobson cross.

It is now just one victory in six for the Latics, who have not won away from home in nearly two months.

Charlton, meanwhile, look a different side under Nathan Jones and moved up to 14th as a result.

Darren Moore felt his Port Vale side “could and should have taken maximum points” at Wigan after the sides shared the spoils in a Sky Bet League One 0-0 stalemate.

Wigan’s Martial Godo came closest to breaking the deadlock, only to fire against a post in the second half.

At the other end, Wigan were indebted to England Under-21 goalkeeper Sam Tickle for pulling off, in the words of Moore, “an outstanding double save” to deny James Plant and Baylee Dipepa.

The point lifts Vale out of the relegation zone, and Moore says that will give them a “psychological boost” for their last five games of the campaign.

“It’s a good day for us at Port Vale, getting the clean sheet and how valuable that point is in terms of the psychological boost of getting out of that bottom four,” he said.

“While we’ll take that today, we know the work isn’t nearly finished, it’s only given us a platform.

“And we have to continue to perform, keep that togetherness, and keep that unity going forward.

“As a group we certainly feel we could and should have taken maximum points, but their goalkeeper has pulled off an outstanding double save.

“The first one, he was going the other way, and then he gets up and makes another save.

“Credit to him for earning them a point, but I just thought both teams were at it, both teams were pressing on, and it was a good footballing match.

“We pressed them high up the pitch, and I liked the way we played on them, and forced errors, which we should have capitalised more on.

“Overall it was a solid performance, and you’re always happy with a clean sheet away from home.”

For Wigan boss Shaun Maloney, it was a third game in a row where his side have failed to beat a relegation-threatened side, after a home draw with Burton and a defeat at Cambridge.

“It wasn’t too bad, it was just OK,” he said. “I know it finished 0-0, but both teams had chances.

“The first 20 minutes was OK, but for the next 25 minutes we became a bit toothless really.

“The second half was a bit better, we had chances to score, as did they…the overall performance was just OK.

“In terms of effort and the mentality of the players – something I really challenged the players on – I couldn’t ask for any more.

“Port Vale are desperate for points, and they went very aggressive during parts of the game.

“When that happens, you have to use the forward passes enough, we just didn’t recognise when to play the forward pass.

“I liked the way the three centre-backs (Charlie Hughes, Charlie Goode and Jason Kerr) played, the forwards they have are good players and I never felt in massive, massive danger from open play.

“Sam Tickle has also made an amazing double save, and he’s just a brilliant player.

“I say it every week, but there always seems to be a moment where Sam influences the result, and that was the case again.

“Those four players were the stand-outs for me.”

Neil Critchley felt his Blackpool side deserved a point at Wigan after suffering a 1-0 defeat that dented their Sky Bet League One play-off aspirations.

An away win would have seen Blackpool climb to sixth in the table on goal difference ahead of the international break.

But Scott Smith’s 26th-minute goal – his first in senior football – proved to be the difference at the DW Stadium, as Wigan climbed to the 50-point mark.

Blackpool had chances to go home with a point, but England Under-21 goalkeeper Sam Tickle denied Shayne Lavery in the first half, before Wigan Academy product Kyle Joseph headed just wide for the visitors after the break.

“Yes, it was a fine line today, and we knew it was going to be like that,” said Critchley. “Looking at some of their recent results, most of them have been low-scoring games, and we knew the first goal would be decisive.

“They got it, from a really great cross but, from our point of view, a poor goal to concede.

“In the second half we were by far the more dominant team, we pinned them back, and it’s not easy to break down 11 men, but we created some decent chances.

“When you do that, you have to take one of them, and we couldn’t do that.

“You’re not going to come here and dominate for 90 minutes, they’re a good team with some good players.

“They play a really good brand of possession football, they overload the middle of the pitch, and they make it really difficult for you.

“I’ve watched a lot of them this season, and they cause a lot of teams a lot of problems with how they play.

“But there was nothing in the game…they got the first goal, and we dominated the second half.

“Overall I thought we deserved to get a point from the game, but it wasn’t to be.”

Wigan boss Shaun Maloney said: “It was two very different halves.

“Blackpool are one of the better teams in the league without the ball, and when you don’t get your build-up play right, they can quickly create chances.

“I really enjoyed the first half, but the second half was the complete opposite.

“We had to defend, and they had a couple of good chances, one a header and one that hit the side-netting.

“But I get just as much pleasure from watching that second-half performance as the first half.

“In the first half, we went very aggressive with the line-up, but we had to play under great pressure – and we did.

“Blackpool are a very good side, they’re going for the play-offs, and the more attacking they went in the second half, the more we had to defend.

“We’ve had to rely on Sam Tickle a lot in these kinds of matches, but I thought we defended pretty well.

“We gave up two chances in that second half, but in other matches we’ve given up a few more.

“In that sense, it was pleasing that we restricted them to that number of chances.”

An own goal by Wigan goalkeeper Sam Tickle decided a low-key encounter as Wycombe claimed a 1-0 win at Adams Park.

The game may not live long in the memory, but the Chairboys celebrated a third win in four games that moved them level on points with their visitors.

Wycombe were gifted the lead after 19 minutes when Josh Scowen’s mishit low cross from the right was fumbled into his own net by Tickle at his near post.

The Chairboys almost doubled their advantage in the second minute of the second half as Beryly Lubala headed a peach of a free-kick from Luke Leahy just wide.

Wigan improved and pressed hard for an equaliser, with Thelo Aasgaard and Charlie Kelman both sending presentable headed chances off-target.

The closest Latics came to snatching a point was in the first minute of stoppage time when Jordan Jones teed up Aasgaard, whose header was brilliantly saved by Franco Ravizzoli.

Fleetwood gave their League One survival hopes a boost with a 4-2 victory against Wigan.

The relegation-battling Cod Army secured their first win in six matches for a vital three points at Highbury.

Neither side could take control in the early stages but Bosun Lawal fired in a thunderous volley to give Fleetwood the lead, before Stephen Humphry levelled the scores just three minutes later.

Thelo Aasgaard then fired the Latics into the lead in the 26th minute but Lawal notched his second goal of the game to ensure the match was even at the interval.

Fleetwood then took the game by the scruff of the neck after the break. Midfielder Gavin Kilkenny put the hosts in front with his first goal of the season, a deflected effort which bamboozled Wigan stopper Sam Tickle.

Striker Jayden Stockley hit the fourth after 61 minutes as he secured the points by heading home a Ryan Broom cross to the delight of the home supporters.

Derby manager Paul Warne watched his players reward him for giving them Christmas Day off as they picked up a 1-0 victory at League One strugglers Wigan.

Curtis Nelson headed home the only goal in the 19th minute, but only the brilliance of Wigan goalkeeper Sam Tickle kept the scoreline respectable.

And Warne – whose side have now won seven of their last eight matches – was a happy man after subjecting one of his former clubs to a third defeat on the spin.

“It was the most pleasing performance of the season, because it was away from home against good opposition and probably the best we’ve played collectively,” he said.

“Even at the end I was making substitutions just to help the lads out, not for any other reason.

“Wigan have taken a couple of good scalps here, so we knew we would have to do a lot out of possession.

“It takes a real understanding of the game, and they’ve been well coached this week to understand how we wanted it to look.

“But then they changed their shape which made it more difficult.

“I just liked the energy and the drive of the team. There were tackles and heads when it was needed. There was also a bit of creativity and some really good performances.

“I gave them Christmas Day off and I wanted them to show me it was the right decision. They paid back my trust in them.”

Warne’s only gripe would have been that the game was not put to bed during the utterly one-sided first half.

“Sometimes you perform at a level then it can all go wrong, so I was anxious,” he added.

“When one down, you throw the kitchen sink and that’s what makes football.”

Wigan boss Shaun Maloney took full responsibility for the disappointing first half that paved the way for the Rams’ victory.

Due to injuries, illness and unavailability, Maloney’s starting XI featured seven academy graduates – with an average age between them of just over 21.

Maloney made a double change at the break, sending on the more experienced Callum McManaman and Jonny Smith, which led to a second half that was far more even, but the damage had been done.

“It kind of felt like two performances in one game, one in each half,” he assessed.

“But I can’t be too critical of the players in that first half, I have to take that one.

“I think I was over-reliant on too many young players in that first half.

“Those young players have been brilliant for me and this football club since I’ve been here, and they’ll definitely come again, that’s for sure.

“Derby are a really good side, good squad, very experienced, a match for anyone at this level.

“Normally when you’re bringing young players in, you’re wanting to drip them in, when the team is in good form.

“In the second half – apart from the first five minutes, when they had a couple of chances – I felt it was much better.

“It felt like we went toe to toe with Derby, and there wasn’t much between the two teams in the second half.”

Peterborough’s League One promotion hopes were dealt a blow as their nine-match unbeaten run came to an end after Callum McManaman’s late winner gave Wigan a 2-1 victory at the DW Stadium.

Wigan had led from the sixth minute when on-loan Fulham winger Martial Godo reacted quickest to Jordan Jones’ cross from the left and prodded home.

After Callum Lang fired just wide, Jones then saw a 20-yard strike crash against the crossbar.

Peterborough were struggling to get anything going, with Harrison Burrows forcing a fine save from Sam Tickle.

The visitors stepped it up after the break, and levelled nine minutes after the restart when David Ajiboye’s cross was drilled home by Kwame Poku.

Ajiboye came close to putting Posh ahead when he sent a left-footed strike whistling inches past the target.

Wigan made them pay when McManaman drilled home from the edge of the box with eight minutes remaining after Posh failed to clear a free-kick.

There was still time for Posh to threaten a leveller, only for Joel Randall to see a shot hacked off the line by Tom Pearce.

Charlton Athletic recorded their first Sky Bet League One away victory of the season at Wigan – but only after a five-goal thriller at the DW Stadium.

The visitors enjoyed an early let-off when Callum Lang hit the bar with a free-kick to open up a three-goal lead by half-time.

Alfie May opened the scoring in the 21st minute at the second attempt after Sam Tickle had clawed away his initial header.

May doubled the lead 10 minutes later with a cool strike into the bottom corner.

And the visitors were in dreamland when Corey Blackett-Taylor made it three with a fierce drive two minutes before the interval.

Only the woodwork prevented substitute Tyreece Campbell making it four at the beginning of the second half.

And that almost opened the door for a remarkable Wigan comeback.

After Thelo Aasgaard hit the bar with a clever flick, the Norway youth international rifled home into the roof of the net with six minutes left.

The home side were further boosted when substitute Stephen Humphrys fired into the top corner in the last minute, but Charlton held on.
