Alan Curbishley's side have, behind Chelsea, been setting the Premiership pace and have taken maximum points from five of their six games so this season. Like ourselves, Charlton's only reverse came against the league leaders.
We head into the game in fourth spot following the 1-0 victory over Fulham on Monday night and the skipper agrees it could well be an intriguing contest at a ground we have enjoyed some success at in recent seasons. We have won on four out of our last seven visits to the Valley.
"It makes it interesting with both teams doing well," considered the central defender. "Charlton are flying at the moment and it is going to be a tough game - no doubt about it. They have a great team spirit and are picking up results, having played six and won five, they are obviously doing something right.
We know it will be a challenge, but it is one we are looking forward to.
There will be a couple of familiar faces in the Charlton team on Saturday with both Chris Perry and Luke Young having made a switch to SE7 from N17. The latter has made something of a name for himself recently as his displays won him England recognition and he featured in the World Cup qualifiers against Wales and Northern Ireland.
Ledley, who played with Luke at both first and reserve team level, says the caps are due reward for the full-back's quiet consistency.
"I think he has always had that potential. He came into the Tottenham team at an early age and put in some good performances. So the potential was always there".
"He moved on to Charlton and it has maybe taken him a while to prove how good he is, but he has always been consistent. He is maybe not someone who stands out but always does a job for you".
"Now he is starting to get the attention his performances deserve and it was great for him to play in the two qualifying games for England."
Another player added to the England squad following his early season exploits for Charlton is Darren Bent, the former Ipswich striker who has seemingly passed the Premiership test with flying colours.
"I have seen him a few times and he was always a great prospect in the Championship," said Ledley on the front man who has netted six goals already this season. "He has come up and shown he is a Premiership player straight away and has taken no time to settle".
"He is scoring goals and presents a danger. He is a player we will have to look out for."
Ledley King is relishing the prospect of Saturday's 2nd v 4th encounter in the Barclays Premiership when we travel to the Valley to take on Charlton Athletic.
