Redknapp was pleased by the contribution of striker Bobby Zamora, who scored QPR's goal, but he admitted he was worried about relying on the former Fulham man, who has only just returned after three months out with a hip injury.
"He is what a Premier League player should be," said Redknapp. "He holds the ball, doesn't give it away and brings players into play. When he doesn't play we haven't got a focal point to our play.
"Jay Bothroyd has come back from loan and he is the only other one who could do that so maybe he needs to be given a chance."
