From “The Guardian”: “Mullins was strongly critical of the ground, which was officially described as good, good-to-soft in places, in a subsequent interview with Racing TV. ‘If the ground is going to be like this, we’re not going to bring them,’ Mullins said. ‘We were promised watering, and I’m not sure the watering we were promised has been done. I’m a little bit annoyed about that…for the majority of the good, big, National Hunt horses, we’d like it a little softer.'”
Since when did he get to dictate what the ground should be like? If he doesn’t want to bring his horses, that is his business.
Reading between the lines, “promised watering” implies he has been in conversation with the clerk and trying to influence the state of the ground for his horses.
Guess what, he will still bring them despite his grumbling. He has still won five Grade 1s this week.
