Zamora fought through the pain barrier, managing 73 minutes before hip and ankle knocks got the better of him.
"Zamora wasn't really fit, he has done a miracle with his ankle ligaments," Redknapp said. "He is playing with an injury today that other players wouldn't have put themselves up to play.
"There are players not playing today with injuries that aren't as bad as Bobby's, that's for sure. He has a go and has done that today.
"You can only play what you've got, and this is the first time I've had Bobby and Remy. I liked the look of them.
"Bobby can hold the ball up and Remy has pace and can score goals. I thought they would be an ideal combination.
"They will be important. If Remy can continue to score and Bobby gives us a focal point, we can play it up to him.
"Bobby played 60 per cent fit today. The physio said a week ago he would be out for six weeks.
"He did his ankle but he has had injections to play, he was so desperate to get out there. The effort he has put in to play was fantastic."
