The 30-year-old had fallen out of favour with manager Paul Lambert at Villa Park and was subsequently signed by his former Tottenham boss Martin Jol on a season-long deal.
Bent netted on his Fulham debut - a 3-1 defeat at home to Arsenal - but managed to hit just six goals in all competitions as the Cottagers were condemned to relegation.
The former England striker was often used as a substitute and he admits that his time in London did not turn out as he initially hoped.
"I've enjoyed my time down here but obviously it hasn't gone well. I haven't played as much football as I would have liked," he told the Express and Star.
"When I first came here I hoped it was going to be a case of playing fairly regularly, but it just wasn't meant to be."
