Every horse is different and has their own personality. Some are easier to train than others and some you have to watch through your fingers as they plough up the gallops.
Willie Mullins has revealed Ryanair Chase hopeful Un De Sceaux is the horse he finds hardest to watch while at work in Closutton.
"The one that is hard to watch is Un De Sceaux because he is a bit like Hurricane Fly, every morning he comes out and wants to race and be competitive," he said.
"Douvan is a lovely, relaxed individual. Holly rides him every day and they go around at their own pace whereas Un De Sceaux wants to race every time he gets on the gallop.
"He pulls, puts his head down and wants to get on with the job.
"You're wondering can he go out there every morning and do that without pulling a muscle or over-reaching or something like that. Those type of horses are harder to mind."
Un De Sceaux is a 3/1(subject to change) shot for the Ryanair Chase after running out an impressive winner of the Clarence House Chase in Cheltenham last month.
