Redknapp said: "I'll let him be the judge (of his fitness). If he plays Saturday to Saturday I'll be delighted.
"That's the priority, but not Saturday to midweek to Saturday. I wouldn't want to take the chance. He can play two games in four days but three games in a week is too much. The league would take preference, if it was a cup game midweek I would rest him.
"He's been unlucky with injury. It's difficult for the lad, he wants to train every day, he can't. He's a great lad and he's so important. When he plays he can make such a big difference. He's that good."
