Charlton Athletic kept their unbeaten run at The Valley intact by holding Portsmouth to a 0-0 draw in a Championship fixture that, while lacking goals, offered plenty of drama, especially after the interval. The home side dominated the first half, creating the clearer opportunities, but both teams ultimately left the pitch without a breakthrough. In the opening 45 minutes Charlton were the more incisive outfit, pressing high and forcing Portsmouth into a defensive posture.

The most notable chance fell to Millen Alli, who had spent the latter part of the previous season on loan with the visitors. In the 32nd minute he found himself on the end of a superb left‑wing cross from Tyreece Campbell and, with the ball at his feet just inside the box, volleyed it over the bar from close range. The effort was a painful reminder of how fine the margin can be; a few inches of better technique could have seen the ball nestled in the net.

Just moments before Alli’s miss, Portsmouth goalkeeper Daniel Bielica made a crucial intervention, using his legs to block a powerful strike from Charlton’s striker Karlan Grant that was heading toward the near post. The shot was struck with considerable force, but Bielica’s quick reflexes kept the ball away from the goal line. Portsmouth’s captain, Marlon Pack, also had a chance to make an impact early on when he rose to meet a corner delivered by Campbell. His header, however, failed to find the target, and the visitors, despite having scored in each of their previous eleven away league matches, went into the break without a single shot on target.

The second half saw Charlton’s goalkeeper Arthur Okonkwo forced into action early, as he stretched a leg out in the 15th minute to smother a low cut‑back from Terry Devlin after a slick passing move. Later, Conor Shaughnessy rescued the away side when he cleared a ball that had been headed back into a dangerous zone by Tyler Bindon, a loanee from Charlton, preventing a potential scoring opportunity. Alli, who was met with boos from the travelling Portsmouth supporters each time he touched the ball, enjoyed one more chance before the interval, this time from 20 yards out, but his shot was comfortably caught by Bielica. The second half began with Portsmouth testing Charlton’s defence again; Okonkwo had to dive low to his left to tip away a strike from Abu Kamara just 20 seconds after the restart.

Portsmouth appeared fresher after a full week of preparation, while Charlton, who had drawn 0‑0 with QPR only a few days earlier, began to show signs of fatigue. Referee Andrew Kitchen dismissed a penalty appeal from Portsmouth left‑back Jayden Meghoma, who claimed that Alli had pulled his arm in the box. Mid‑field battles continued, with Oliver Skipp making a clean tackle to dispossess Adrian Segecic on the edge of the area after a turnover by Bindon. Segecic later wasted a chance, firing a tame shot at Okonkwo from inside the box, while Colby Bishop failed to convert a close‑range cross from Ryan Kavuma‑McQueen in the 81st minute.

As the clock wound down, Charlton dug deeper into their bench. Conor Coventry curled a ball into the area from a short‑corner, and Shaughnessy made a vital defensive block from a Grant strike.

The home crowd appealed for a penalty when Miles Leaburn went down after a challenge with Benjamin Arthur, but the referee saw no foul. After the final whistle, both managers reflected on the match. Charlton’s boss Nathan Jones praised his side’s overall display, especially the first half, saying, "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." He continued, highlighting the missed opportunities: "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." Jones also spoke about squad availability, noting that Charlie Kelman had returned to action and that the team hoped to see Josh Edwards back soon. He added that the international break would give the squad a chance to recover, especially after a demanding run that saw five defenders play continuously since a match against Tottenham. Portsmouth manager John Mousinho, on the other hand, emphasized the positives of securing a clean sheet away from home.

"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," he said. Mousinho acknowledged that the team had struggled to test the opposition goalkeeper in the first half but felt the game opened up after Charlton’s midweek match, providing more opportunities.

He concluded with optimism about the squad's attacking potential, stating, "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 sides left the encounter with a point each, maintaining their positions in the league table and keeping their defensive records intact.

The match served as a reminder that, in the Championship, a single moment can decide a result, and that resilience and concentration are as valuable as finishing ability. The draw also sets the stage for the upcoming fixtures, where both Charlton and Portsmouth will look to convert the chances they created into the goals they need to climb the table.
