After watching Concert Hall win the Group 3 Weld Park Stakes in the Curragh today, Aidan O'Brien commented on his Group-race double yesterday.

Tenebrism started the ball rolling when she came home very strongly to take the Group One Cheveley Park Stakes over six furlongs at Newmarket in the hands of Ryan Moore.

O'Brien said: “She looked incredibly special in Naas when she took off in the last furlong [when landing her maiden in March] and was just ready to go racing yesterday.

“She’s obviously a good filly. You would like to run her over seven to see what would happen for next year but it looked like the way she went to the line (at Newmarket) that she could get seven well.”

Luxembourg was then impressive when winning the Group 2 Beresford Stakes at the Curragh by the guts of five lengths.

“He’s a lovely horse and was showing loads before he went to Killarney. He came forward every week after that and it was a lovely second stage for him," the trainer said.

“The plan was to come here and then he might go for the Futurity if he stays well. Sometimes this time of the year horses can go off because he is a big horse.

“He has plenty of class and is not short of pace. He goes through his work very well.”
