Charlton v Portsmouth: prediction, lineups and tips

Charlton have made the sort of start to the Championship season that nobody outside The Valley predicted, and Saturday brings a chance to underline it against a Portsmouth side that already looks short of last season's cutting edge. N. Jones's side sit fifth after six games, a point outside the top four, and they go into this one on the back of an unbeaten run in five of their last six league outings. Portsmouth, by contrast, have lost three of their last five and have not kept back-to-back clean sheets all season.

The Addicks have taken 11 points from a possible 18 this term, sitting fifth with a goal difference of minus one, a quirk of two heavy defeats offsetting a run of tight, low-scoring wins. Their last three results, a win over Preston, a draw at West Brom and a draw at home to QPR, tell the story of a side that grinds out points rather than overwhelms opponents. Jones's team have scored just six goals in six league games, level with their against tally of seven, but they have kept two clean sheets at The Valley and lost only once at home.

That one home defeat came against Stoke City, beaten 4-0 away from home on 5 September, a result that still stands as the outlier in an otherwise solid opening block of fixtures. Charlton have won two of their three home league games this season and conceded just once at The Valley, a record that will worry a Portsmouth side who have won only once on the road.

Portsmouth arrive with three defeats in their last five matches, J. Mousinho's side having lost at home to Derby and away at Bristol City either side of a home win over Cardiff. Mousinho has been candid about the scale of the rebuild at Fratton Park this season, telling BBC Radio Solent that Charlton "have had a really good start" and pointing to their own busy summer of recruitment as a factor in a slower start than hoped.

Pompey have scored in four of their five league games but have also shipped eight goals already, including three in defeat at Bristol City. A win at The Valley would settle some of the early-season nerves, but recent history at this ground is not on their side.

Mousinho was asked about the challenge posed by Charlton this week. He said: "Charlton have had a really good start. They've had a really busy summer as we have in terms of recruitment in bringing players in, they also had a really good season back in the Championship after their promotion from League One."

Charlton's WWWDLD form line flatters a side that has actually drawn two of its last three, but the underlying pattern, three wins from six and only one defeat, still marks them out as one of the division's early over-performers. Portsmouth's LWLLW reads far more erratically, two wins bookending three defeats, and their away form in particular has been the problem: one win and one loss from two league trips this season. Charlton's steadier baseline, built on defensive solidity rather than firepower, gives them the edge going into this one.

Charlton sit fifth on 11 points from six games, level on points with QPR and Swansea in fourth and third but with an inferior goal difference of minus one. West Brom top the table on 13 points, so the gap to the automatic promotion places is not yet significant this early in the season. A win here would move Charlton above QPR and Swansea on points and keep them firmly in the play-off picture heading into the international break.

Portsmouth have played five games to Charlton's six and sit further back, with three defeats already on the board. A repeat of last season's 18th-placed finish is the thing Mousinho will be desperate to avoid, and a fourth defeat in six would leave Pompey looking anxiously over their shoulder rather than up the table this early in the campaign.

Charlton have the historical edge in this fixture, winning four of the last ten meetings to Portsmouth's three, with three draws. The pair have shared an average of 3.1 goals per meeting, both teams have scored in seven of those ten games, and eight have gone over 2.5 goals. The last meeting, back in February, finished 1-3 to Portsmouth at The Valley, a rare away win in a fixture that has otherwise tended to favour the home side.

That February result looks increasingly like an outlier given where both squads stand now. Charlton have strengthened and tightened up defensively since then, while Portsmouth have shipped goals at a worrying rate in the opening weeks of this campaign. The H2H goal trends, an over 2.5 rate of 80% and a BTTS rate of 70%, still point towards an open game, and neither side's current form suggests that pattern is about to break.

Portsmouth have the ball more, averaging 54.2% possession in their last five games to Charlton's 36.3%, and they get more shots away too, averaging 16 attempts per game to Charlton's 10.17. But Charlton have been the more clinical, sharper defensive unit of the two, conceding at a lower rate (1.17 per game against Portsmouth's 1.6) despite seeing far less of the ball. Portsmouth's extra possession and shot volume count for little if Charlton's low block continues to force them into low-value chances, and that gap, control versus efficiency, is the one to watch.

Kick-off is at 15:00 BST on Saturday. This fixture falls inside the UK's Saturday 3pm blackout, so it is not being shown live on TV or streaming anywhere in the UK. Fans can catch highlights on Match of the Day later on Saturday evening, or follow our live blog for updates throughout the game.

Charlton's defensive record at The Valley is the strongest angle on this card, with Portsmouth shipping eight goals in five league games and struggling to string clean sheets together. The value sits with the hosts across the match result and goals markets, though the head-to-head pattern of BTTS and over 2.5 goals keeps this from being a banker.
