Redknapp admits he is short of striking options, with the hip problem hindering Bobby Zamora - who got their only goal at the Liberty Stadium - a particular concern, while France striker Loic Remy has missed the last two games with a groin strain.
"We have a chance if Remy can come in and score some goals and show what he can do, and we can get Bobby out on the pitch," he said.
"The problem with Bobby is we have to stop him at half-time. If we played straight through he could probably manage 70 minutes, but stopping at half-time he seizes up then he can't move.
"When he plays he's different, he can move, hold the ball up, he is someone we can play up to. Without him we don't have someone who can lead the line."
