Karlan Grant’s first goal since rejoining Charlton on a free transfer from West Brom secured a 1-0 victory against struggling Preston North End.
The win keeps Charlton as the only side in the Championship with a perfect record, making it three wins from three matches this season.
It marks the first time Charlton have won their opening three second-tier matches since the 1992-93 campaign, a notable milestone for the south London club.

The result means Southampton have now wiped out the four-point deduction they received for their Spygate controversy.
