Charlton were beaten 1-0 by Portsmouth on their 25th anniversary back at the Valley.

Josh Magennis headed into his own net on 47 minutes to leave the Addicks winless in three league games.

Here are five things we learned…

The lack of creativity is worrying

Charlton barely created anything in 90 minutes against Peterborough before scoring two late goals to rescue a point. It was the same story against Portsmouth, but without the goals.

Ricky Holmes had a snapshot easily tipped over and Leon Best saw a header saved late on. And that was it in terms of chances.

The return of Billy Clarke and Ben Reeves should help bring some much-needed creativity and attacking threat to the team.

Karlan Ahearne-Grant was unlucky to be left out

Ahearne-Grant scoring three goals in as many games put him in serious contention to start against Portsmouth.

But the young Charlton attacker was overlooked for the fit-again Clarke. It was a tough decision for Karl Robinson to make.

Ahearne-Grant replaced Clarke with 15 minutes to go but there wasn't enough time to make an impact.

Hopefully his new-found confidence won’t take a hit.

There is no need to panic yet

It’s still only two defeats in 12 league games for Charlton who have been playing with an injury-hit squad. Performances haven't been great in recent weeks but first-team players are beginning to work their way back to full fitness.

Clarke, Reeves and Chris Solly returned yesterday, Jason Pearce and Harry Lennon returned last week and Fosu is close to recovering from a quad problem.

And in a month where the Addicks take on promotion rivals Blackburn and Wigan, those six players could play a crucial role.

Tariqe Fosu is needed back ASAP

Fosu’s trickery and pace has been desperately missed.

Mark Marshall has come in for the winger, but has not hit his best form yet.

Fosu is the Addicks’ top scorer with seven goals. So the sooner the former Reading man is fit, the better.

Robinson acknowledged Fosu’s absence in his post-match press conference saying the 22-year-old has been a bigger loss than they thought he’d be.

The Valley atmosphere was terrific

This commemorative match was always going to attract numbers. Charlton played in front of 16,361 supporters - the highest attendance since their return to League One.

The atmosphere before and during the game was outstanding, even when the Addicks went a goal down.

It’s just a shame the team couldn't get the three points.
