Clark Robertson’s 89th-minute equaliser cancelled out Joe Aribo’s stunning solo effort.

Charlton spurned glorious opportunities to put the game to bed and ultimately paid the price.

Here are five things we learned…

The draw sums up Charlton’s season so far

Take the lead, waste chances in front of goal, concede an equaliser… or… waste chances in front of goal, concede and lose the game.

That’s happened against Plymouth, Gillingham, Walsall, Bury, MK Dons, Scunthorpe and now Blackpool this season.

Just imagine where Charlton would be if they were able to kill teams off?

It’s so frustrating.

Defending set-pieces is becoming a serious problem

Charlton have conceded three goals in as many games from dead-ball situations.

And their own corners and free-kicks were dreadfully executed yesterday, something Karl Robinson acknowledged in his post-match press conference.

There seemed to be a lack of decisiveness in Charlton’s box when the ball was floated in for Blackpool’s equaliser.

And that has to change immediately if the Addicks are going to get back to winning ways.

Leon Best’s bad luck continues

Best scored an own goal after being on the pitch for just three minutes in the 2-0 defeat to Blackburn last weekend.

He led the line against Blackpool and caused problems for their backline. He missed two golden opportunities to double the Addicks’ lead, though.

And just as Best was growing into the game in the second-half, he was forced off with a hamstring injury, which is likely to rule him out of the festive period.

It’s such bad luck and timing for the striker, whose deal runs out at the end of next month.

A play-off spot with a depleted squad over Christmas isn't too bad

Despite winning once in seven league games, Charlton are still in the top six.

That’s a testament to their early season form which saw them close in on the automatic places. Injuries have seen a top two finish slip away (for now), but a play-off spot is still very achievable.

With Tariqe Fosu, Ricky Holmes, Jake Forster-Caskey, Chris Solly, Patrick Bauer and Jason Pearce to come back, there is no reason to believe Charlton won’t improve.

Johnnie Jackson’s still got it

In only his second league start since April, Jackson played well. The club captain, 35, rolled back the years while filling in for Forster-Caskey and Ahmed Kashi.

The player-coach knows his game-time will be limited nowadays, but showed he is still a very reliable option for Robinson.

When he was needed, he didn't let anyone down. Jackson was a calming presence and kept Charlton’s midfield ticking.
