Manchester City were swept aside 4-0 in a dream start on day one but Alan Curbishley's men were soon brought back down to earth with a 3-0 thumping at Everton three days later.
Since then the Addicks have won praise all round for more than playing their part in a 5-3 defeat at Arsenal and coming from behind to snatch points against Southampton and, last Sunday, at Derby where they were 2-0 down with an hour on the clock.
Jonatan Johansson made an immediate impact by grabbing both equalising goals against Southampton and Derby.
The Finnish international was snapped up for £3.25m - just short of the club record - from Glasgow Rangers where he netted 24 goals in 65 games.
Johansson is likely to be partnered by in-form Andy Hunt. He has scored three times already this term including a double against Arsenal's famed defence.
Signed on a Bosman in June 1998, Hunt disappointed in Charlton's last Premiership campaign with just seven goals but like the club, recovered to take Division One by storm with 24 goals, 25 in all competitions, last season.
Charlton's record £4m buy Claus Jensen opened his account with the first goal at Derby and Graham Stuart also provides a threat from midfield - the former Chelsea and Everton star has scored twice already this term.
Many believed Mark Kinsella, a class act in the centre of midfield, would be on his way when Charlton were relegated in 1998-99 but the club captain and inspiration led Addicks back to the top flight. Capped 16 times by Republic of Ireland, Kinsella has the lot in central midfield and scored against us on our last visit to the Valley two seasons ago.
Veteran John Robinson completes the midfield with Shaun Newton and winger Kevin Lisbie - impressive as a substitute at Pride Park - both pushing for starting places.
The defence has a settled look to it. Promising goalkeeper Dean Kiely is the club's number one and a Republic of Ireland international keeping out flamboyant Sasa Ilic - the Wembley hero from two seasons ago.
Radostin Kishishev caught the eye playing for Bulgaria against England in June 1999 and Curbishley brought the right-back to the Premiership from Litets Lovech in a £300,000 rising to as much as £1.8m after appearances.
Chris Powell is a consistent performer at left-back while centrally Richard Rufus will be partnered by either Carl Tiler or Steve Brown.
Both have suffered red cards this season with Brown sent off when replacing the suspended Tiler in the draw at Southampton. Tiler played at Derby so expect him to get the nod on Saturday.
Charlton's return to the Premiership has produced a mixed bag so far - and a new hero.
