Blackburn Rovers striker Benjani is keen to hand Sam Allardyce a major fitness boost. Benjani, 32, who was a free agent after being released by Manchester City, had to allay concerns over a knee problem suffered during a spell at Portsmouth.
He told BBC Radio Lancashire: "I didn't have any problem proving my fitness.
"I'm happy here - I hope to score goals and if I'm fit I know I will have to fight for my place."
He added: "The Premier League is the best league in the world and I always wanted to stay here.
