Chris Waller has hit back at English racing commentator Matt Chapman, who on Tuesday questioned the form of legendary Australian mare Winx.

At Tuesday morning’s Cox Plate barrier draw, ITV host Chapman mounted a case for Godolphin raider Benbatl, suggesting that the view abroad was that Winx had been beating ‘fairly moderate horses’ in Australia.

Waller, speaking on radio station SEN1116, took umbrage at the comments, suggesting they were disrespectful and labelling him a ‘bit of a dickhead’ in the process.

“I’ve taken those comments in and I was very, very surprised and disappointed to the fact that I think he’s a bit of a dickhead for saying it really,” Waller said.
