The midfielder is yet to catch fire since his loan switch from QPR.
"He's gifted and has got natural ability," Bent told Fulham's Google+ Hangout.
"He hasn't even started to fulfil his potential yet. Once he has, he could be a real handful because he's got everything.
"He hasn't played many games. Once he's 100 per cent fit he will be flying.
"We see it every day in training. He's got two good feet, can dribble and pass."
