Jo Durie, who is working for TV at the Australian Open, on Johanna Konta matching her run to a Grand Slam quarter-final in 1984.
"I thought she had blown it but then she broke back and I knew she was going to do it. I am so excited.
"Hopefully she'll get this win out of her system. She must not think she should win but should focus on playing her game. I genuinely think she has a chance of making the semi-finals, so fingers crossed."

"In my estimation Jo Durie is the happiest person apart from Johanna Konta in the whole of Melbourne. She watched every ball of Konta's match and was cheering her on alongside Annabel Croft."
