Nathan Jones believes Friday’s home game against Northampton Town is the club’s biggest game in nearly five years.
The Addicks can guarantee the minimum of a place in the Sky Bet League One play-offs with a win at The Valley on Friday.
Speaking to CharltonTV, Jones said: "It’s as important a game as Charlton have had in many a year, probably since the final game of Covid when they got relegated to the division. It’s probably that important. We’ve put ourselves in a wonderful position and we’ve got to keep hammering that home now.
"It’s going to be a real tough game - we saw against Lincoln that if we’re not at it and we don’t make the right decisions before, during and after games then we come unstuck. We’ve got a week to prepare, but then it’s going to be three season-defining days."
