With Sean Davis now fit for tomorrow's UEFA Cup tussle at Vitoria Guimaraes, Redknapp told the Portsmouth News: Redknapp said: "I'm weighing it all up at the moment. It's a bit of a dilemma.
"Sean's looking okay but we have got to be careful with him. He's only just come back from a groin tear. You don't want it to happen again. He's got to be looked after right. You don't want him to rip it completely so he is out for months.
"Then again, we need Sean back. We need everyone we can, so we will have to wait and see how he gets on in the build-up. Hughesie has come in and done excellent, though.
"Whenever he plays he never lets you down. When you think he has not really trained after being injured since the start of the season, it's a fantastic effort, it really is. I remember when I bought him from Bournemouth six years ago for a combined £75,000 with Eddie Howe.
"That was value for money for sure. He understands the game and that's one of his biggest assets. It may sound a silly thing to say but he understands football. He senses danger and knows what he is doing. He can see trouble at the right time and understands how to deal with it. Hughesie's got a great footballing brain.
"It's a decision that needs to be made but it's going to be a tough one."
