Portsmouth manager Steve Cotterill is still looking to strengthen his squad despite bringing Benjani back to Fratton Park.
The striker left Pompey for Manchester City in 2008 and he was a free agent after leaving Blackburn Rovers over the summer.
Benjani signed a one-year deal on Saturday, although Cotterill remains in the hunt to bring more fresh faces to the club.
Pompey tackle Reading on Tuesday night and Cotterill is looking to swell his ranks before the big kick-off.
Bari striker Erik Huseklepp has been linked, but Pompey's boss has refused to confirm whether the Norwegian is on his radar.
"I'm still hopeful of the loan and a permanent," he told The News. "I might be hopeful of two permanents. That may be before Reading, I'm not sure."
Benjani was a popular player during his previous two-year stay on the south coast and Cotterill believes his return has provided a boost.
"I've felt we've needed firepower," he added on Benjani. "I think we probably still need another striker and maybe another after that.
"Benji brings energy and maybe for a year it might be what we need. He will give everyone a lift - he has done already.
"He turned down a contract at Blackburn, so I rang him and 24 hours later we were finalising his contract in a car park.
"It is amazing how quickly it happened but we're pleased to get him. Now we have to assess when he goes on the pitch.
"It might be one where he goes in the deep end and we see what we get from him. I don't know yet."
