"Absolutely none!" Waller replied emphatically.
Waller says Australia's favourite horse will be sent for a spell with staff keeping a very close eye on her. "We will talk to Sheikh Mohammed and he will make the decision for the future".
Therefore it was not unreasonable to wonder about the quality of competition Winx had faced in her Cox Plate hat-trick.
Chris Waller's seven-year-old claimed the Group One heat for the last three years, putting her level with Kingston Town who also won three renewals between 1980 and 1982.

"She will tell us when she's ready", trainer Chris Waller said.
"It's very hard to say what is the best of the best, but as a day it is one I will never forget".
"Not only is she good enough to win these races, she is good enough to overcome problems and still win".
That might be the case, but this time around she beat a high-quality European challenger who was at the top of his game, who was racing over his ideal distance and had been given every chance by his rider, Oisin Murphy.
"It's the time to enjoy a great horse that did smash Benbatl up and I wanted to see that", Chapman said.
Alan informs listeners just how risky it can be to keep running such a valuable mare.
He admits the challenge of the tight turning Moonee Valley track is a concern.
Winx is a seven-year-old now and seemingly defying time, racing at an age most mares have been retired to the breeding barn.
"With numerous males we don't see the best ones beyond their four-year-old seasons".
"They came, we conquered".
"That is why we are so lucky with Winx because her owners bought her to race and because she is in the form that she is and she is happy to race, they (owners) are happy to continue to do so".
