Charlton Athletic continued their impressive run of unbeaten performances at The Valley, securing a 0-0 draw against Portsmouth in a Championship clash that, while lacking goals, offered plenty of excitement, especially after the break. The home side dominated the opening half, creating the most clear‑cut opportunities and looking the more threatening of the two teams. In the 32nd minute, Millen Alli, who spent the latter part of last season on loan at Portsmouth, found himself on the receiving end of a perfect left‑wing cross from Tyreece Campbell.

Alli’s volley from close range sailed over the bar, a missed chance that could have broken the deadlock. Earlier, Portsmouth keeper Daniel Bielica had been forced to use his legs to parry a powerful strike from Charlton’s Karlan Grant at the near post, underscoring the fine margins that defined the first half.

Portsmouth captain Marlon Pack also made an impact, rising to meet a corner delivered from an early Campbell cross, but his header failed to find the net. The visitors entered the match on the back of a remarkable run, having scored in their previous eleven away league fixtures, yet they did not register a single shot on target before the interval.

Charlton’s goalkeeper Arthur Okonkwo was called into action in the 15th minute when he stretched out a leg to block a low cut‑back from Terry Devlin, showcasing his alertness in the early stages. The second half began with a flurry of activity.

Conor Shaughnessy rescued Portsmouth when he cleared a ball off his own goal line after Charlton loanee Tyler Bindon headed a deep cross into a dangerous area. Alli, who was met with boos from the travelling Portsmouth supporters each time he touched the ball, enjoyed one more chance before the break, striking a 20‑yard effort that sailed straight to Bielica. The visitors, however, seemed more vigorous after a full week’s preparation, while Charlton, having drawn 0-0 with QPR just three days earlier, began to show signs of fatigue.

Referee Andrew Kitchen dismissed a penalty appeal from Portsmouth left‑back Jayden Meghoma, who claimed he had been pulled on the arm by Alli. Meanwhile, Charlton’s Oliver Skipp produced a textbook sliding tackle to dispossess Adrian Segecic on the edge of the box after Bindon lost possession. Segecic later wasted a chance, shooting weakly at Okonkwo from inside the area, and in the 81st minute Colby Bishop failed to convert a close‑range sliding finish from a cross by Ryan Kavuma‑McQueen. As the clock ticked down, Charlton dug deep into their bench.

Conor Coventry curled a ball into the box from a short corner, testing the Portsmouth defence, while Shaughnessy made a vital block on a shot from Grant. The home crowd appealed loudly for a penalty when Miles Leaburn went down after a collision with Benjamin Arthur, but the referee waved play on. Post‑match, Charlton manager Nathan Jones praised his side’s display: "The performance was really good, especially in the first half. We created some excellent chances, looked a threat and controlled the game.

When you look at the game we had against them here last season, it was the polar opposite. Our midfield two were excellent and our wide ones carried a threat. We had the absolute clear‑cut chance of the game. If we had scored the first goal, especially in the first half, then we are very difficult to beat here.

There probably won't be an easier chance in the Football League today than Millen Alli's chance. He is three yards out. He just needs to guide it on target and he scores.

He managed to put it over. Karlan Grant had a great chance.

It was a really good game, end to end and two really committed sides. Portsmouth beat us twice last season, so it is a better result than we had last year. Overall the performance level was there and it's a clean sheet. You can see some partnerships building.

We want to get all our injured players back. We had Charlie Kelman back today and hopefully we get Josh Edwards back next week, so that is another one.

We will be in a stronger position after the international break. The five defenders have had to go from the Tottenham game until now, really putting in proper shifts. To keep three clean sheets shows that." Portsmouth manager John Mousinho echoed a similar sentiment, noting the positives despite the lack of a goal: "You come away from home and draw 0-0, then a clean sheet is the really positive aspect of the game.

We created some really good chances in the second half but just didn't put the ball in the net. Mixed emotions, because we could have won it.

We got into some good spots but didn't really test the goalkeeper in the first half. With Charlton playing Wednesday night we thought we'd have more joy as the game opened up, which we did.

There are some really good signs, but we need to keep improving. We put the chances in the back of the net last week.

We didn't do it this week. The top end of the pitch, we have got quality and goals there, which I think will come." Both managers highlighted the importance of maintaining defensive solidity while working on converting the numerous opportunities they generated.

The match also offered a reminder of how fine the margins are in the Championship; a single shot on target could have altered the narrative entirely. As the season progresses, Charlton will look to build on this resilient defensive display and add goals to their repertoire, while Portsmouth will aim to rediscover the clinical edge that has seen them score in eleven consecutive away games.

The encounter, though goalless, provided fans with a glimpse of tactical adjustments, player resilience, and the relentless pursuit of that elusive breakthrough. It also served as a platform for younger talents like Alli, Campbell, and Shaughnessy to showcase their potential under pressure. With the international break looming, both sides have a chance to regroup, heal injuries, and return stronger for the next round of fixtures.
