Sam Thomas and TonyMcCoy have ridden the 11-year-old in the majority of his recent races but Walsh was on board when hedisappointed at Aintree in April.
With Walsh likely to ride Kauto Star if the pair both line up in the Gold Cup in March, owner Barber is sure the situation will sort itself out nearer the time.
“I’m very excited about it. I can’t wait to go over for the Lexus,” said Barber. “It’s a left-handed track – he much prefers it that way as we all know – it’s over three miles and the girl who has been riding him out this season says he feels as good as ever.
“At the moment he’s not showing any signs of his age. You just need to look at Kauto Star the other day. I’ve no worries on the age score at all so let’s hope he comes forward and does his very best.
“What I would love to happen is win this and then go and win the Gold Cup. I would say those two races will be it this season. It would be absolutely fantastic if he could make it to the Gold Cup again.
“Ruby definitely rides him in the Lexus and then we’ll go from there. If he rides Kauto Star in the Gold Cup, we’ll find somebody else I expect.”
