He said: "Other than Aaron Lennon, we haven't got anyone to play wide right really - apart from Bentley, and he obviously wants to move.
"You need someone who wants to play and there's no one else to stick out there. I just genuinely feel Beckham could come here and do a good job for us.
"Bentley did well at the end of last season. It's difficult. He's not happy because he's not playing and I understand that. I wouldn't want him to sit there and say, 'I'll take my wages'.
"He needs to play somewhere and there are a few clubs that want him."
