Taarabt claims he did not sleep for three nights as he mulled over his penalty miss.
Redknapp joked: "It's funny that because neither did I!
"But he's OK. He's fine. He'll get over it. He felt he let people down but he didn't. Everybody misses penalties at some time. Ronaldinho even missed one the other night.
"He's confident he can take the penalties and he is the penalty taker.
"If he gets another one, I'm sure he'll score."
