Maria Sharapova delivered a delicious put-down as the issue of grunting reared its head again ahead of this morning's Australian Open women's semi-finals.

With three of the four protagonists – Sharapova, Victoria Azarenka and Petra Kvitova – known for the noisy habit, the Russian was asked about beaten quarter-finalist Agnieszka Radwanska's complaint that her grunting was off-putting.

'Isn't she back in Poland already When did she get a chance to say that' asked Sharapova, who was due to face Kvitova at 4am UK time.

'Nobody important has told me to change or do anything different. Right now there's no rule change. I don't hear there will be one, so it doesn't matter what my answer would be.'
