Finn Jonatan Johansson ruthlessly extended Chelseas travel-sickness problems by sending jubilant Charlton on their way to a first six-pack of Premiership wins this season.

Tormentor Johansson struck 10 minutes before half-time and Martin Pringle hammered the last nail into their derby rivals coffin as the Blues, now without a win in 13 away games, died on their feet.

The Addicks began the day one place above their neighbours and their ensuing victory courtesy of Johanssons sixth league goal of the campaign and Pringles first - was a triumph for fervour over finance that seriously questioned the need to chase Dons striker John Hartson.

The Finnish international was played in by a dinked pass from former Blues dazzler Graham Stuart, and despite pressure from Marcel Desailly, managed to tuck the ball inside the far post from just inside the penalty area.

The goal punished Desaillys slackness, but the Frenchman did get a reprieve five minutes later when referee Paul Durkin dished out only a yellow card for his blatant hack on a clean-through Johansson five minutes before the break.

Changeable Chelsea have many guises, and manager Claudio Ranieri again chose to keep the fans guessing.

Jody Morris was handed his first starting role since September while, strangely, Dennis Wise was preferred in the right wing-back role vacated by Albert Ferrer.

The Addicks gave new signing Mark Fish his home debut and John Salako his first start of the season, and it was the former Crystal Palace man who tested Ed de Goeys reflexes early on with a drive from distance.

The Dutch keeper then pulled off a superb one-handed save as Johansson was played in by Claus Jensen's through-ball, but the Finn could not be denied from a similar move on 35 minutes.

Chelsea were not short on chances themselves, just accuracy. Morris picked out Gianfranco Zola with a cross-field ball worthy of former boss Glenn Hoddle, but the Italians shot was a fraction too high and clipped the bar.

Gustavo Poyet smashed a volley wide, then Jimmy Floyd Hasselbaink came within inches of the far post with his first sight of goal.

The arrival of Tore Andre Flo and Eidur Gudjohnsen after the break failed to enliven the visitors even though they were enjoying plenty of possession.

Instead, Charlton should have doubled their lead when Frank Leboeuf left a back-header woefully short but Stuart couldnt capitalise.

Pringle made sure of a deserved victory by heading home a corner in the final minute.
