In such a tight division as this season's Championship, a run of four successive defeats is going to put any club in a poor situation.

Charlton have now joined their visitors in a bottom half battle, so both teams really need something from this game as we head into a hectic December period.

📈 Charlton v Portsmouth Form & Stats

Charlton have suffered in recent weeks, their previously rock-steady defence has been torn apart, conceding 12 goals in four consecutive defeats. However, after 40 minutes of their last match against league leaders Coventry, the Addicks probably should have been at least 2-0 to the good such was their performance.

This indicates to me that the players are still very much on board with Nathan Jones and it is probably a matter of time until results turn back the other way.

However, Charlton's performance data has really slid as well as their results. Their last five matches has seen their xG ratio dive down to be the worst in the division. They are now ranked 22nd for expected goals for, and are down to 19th for xG against.

Portsmouth aren't in a good place either, though. They have won only once in nine Championship matches, and away from home it is worse. Their only away win this season in the league was their first away match at Oxford, since then they have drawn three, but lost four, including their last three in a row.

Just as concerningly, if not more so, the performance data is pretty clear on how Pompey have struggled, especially on their travels. They have yet to win a single xG battle, i.e. they have not once created better goalscoring opportunities than their opponents in an away game, and this has led to a xG ratio difference of 0.84xG for versus 1.88xG against in road matches, giving around a goals worth of chances away to their hosts.
