"If you create chances, you may be able to score goals against Reading, certainly on their travels.
"We will make sure that we emphasise that point.
"It would great if we could (go fourth). We've got points on the board, and we're very hopeful. We're there on merit. We've only been beaten once."
"I look up to him. It's always good to see Sparky. He speaks sense and always has done.
"He's a man of few words but when he spoke it made sense and made you think.
"Some of the things he said when I was 21 still stick with me today and I use them in my footballing life. To me he was just Mark Hughes the legend."
