The winger made history in his Tykes bow as a 15-year-old in 2008, becoming the youngest player ever to appear in a Football League match, yet has only gone on to make eight league starts for the South Yorkshire outfit.
However, with Barnsley desperately trying to preserve their Championship status, Flitcroft has started Noble-Lazarus in their last three outings and admits his impressive performance in the 2-0 win over promotion-chasing Hull on Saturday hinted at a bright future.
Flitcroft even suggested the 19-year-old could follow in the footsteps of former team-mate John Stones, who left Oakwell for Everton in January.
"I've got high hopes for that kid," Flitcroft said. "I was worried about Reuben a few months ago, I wasn't too sure if he'd really make the grade like Stonesy has done.
"But he's proved everything, he's turned into a man."
