The England international joined Martin Jol's side on a season-long deal on Friday, having been frozen out of Lambert's plans at Villa Park. 

And the 29-year-old fired a parting shot at the Scottish boss.

"It was horrible. It wasn't so much the injuries - although they didn't help - it was just the uncertainty," Bent explained. 

"I understand that not every player can be every manager's cup of tea.

"But to be alienated like that, to be kicked out of the first-team dressing room when I've played a long time and when I'm an international, just felt a bit disappointing.

"There were times when I was thinking, 'Do I really deserve this?' to be treated like that was bad."

The former Sunderland striker is now targeting a return to form at Craven Cottage as he seeks to force his way back into the England side, having not played for his country since November 2011. 

Bent, who has four international goals from 13 caps, continued: "I'm not just hungry to play football again at Fulham, I'm absolutely starving.

"I've missed out on a couple of major competitions with England, so I just hope this is my year."

Bent was an unused substitute in Fulham's 1-0 win over Sunderland on Saturday.
