Cardiff City boss Russell Slade says Tuesday's visit to Rotherham could be the time to "unleash" Alex Revell.
The Bluebirds have scored only five goals in nine games and Slade wants his strikers to be more ruthless.
The 31-year-old joined Cardiff from The Millers in January and could relish an outing against them.
"Going back to his old club maybe that's the ideal time to unleash him," said Slade.
"It could let him show us what he's got because he's hurt me a time or two since since I got rid of him at Orient."
Slade was manager of Leyton Orient when Revell was sold to Rotherham in 2011, and the striker was his second signing after taking over from Ole Gunnar Solskjaer at Cardiff.
However, Revell has only scored once in 10 matches since his arrival.
The Bluebirds travel to the New York Stadium off the back of a 1-0 home defeat against Wolves on Saturday, when Revell made an appearance off the bench..
Although six places higher than 21st-placed Rotherham in the Championship, only four points separate the teams with Slade concerned about his strike force's lack of success.
"I think as forwards we need a goal," he said.
"The last two from [defender] Sean Morrison and [midfielder] Arun Gunnarsson - and we need our forwards or your forward thinking players scoring and contributing, and I think if one of those score it can only be a good thing.
"If there's a criticism at the minute it's that we need a bit more ruthlessness when we get chances - one thing we saw at the weekend against Wolves is they take their chances."
