Jose Riga earned his first win since returning to Charlton Athletic as they routed fellow Championship strugglers Rotherham United 4-1 at the New York Stadium on Saturday.
Charlton had failed to win their last 11 league matches, a run that prompted the club's hierarchy to re-appoint Riga this month.
Simon Makienok settled any visiting nerves with a fourth-minute opener, and although Chris Burke's first Rotherham goal levelled proceedings, Igor Vetokele restored Charlton's lead shortly before the break.
Makieno's second stretched Charlton's lead and luck was with the visitors when Rotherham's Jonson Clarke-Harris blazed a 74th-minute penalty high into the stands.
Charlton made Rotherham pay as Ademola Lookman completed the rout to earn Charlton a first win since November, leaving them a point adrift of safety.
