Gassan Ahadme scored a last-gasp extra-time winner as Charlton escaped with a thrilling 4-3 FA Cup win at National League Southend.
Miles Leaburn and Zach Mitchell had put the Addicks in control during the first half but their non-league opponents fought back through a Jack Bridge penalty and Oliver Coker’s 52nd minute strike.
Matty Godden put Charlton back in front midway through the second half but Joshua Edwards’ own goal in stoppage time sent the tie to extra time.
However, it was Charlton’s turn to strike in time added on as Ahadme sent the Addicks into round two.
