Aidan O'Brien has confirmed that Excelebration and not So You Think will clash with Frankel in Saturday's JLT Lockinge Stakes at Newbury.
The four-year-old chased home Frankel three times when trained by Marco Botti last year, winning his other three starts. He made a fine start for his new trainer when winning last month's Gladness Stakes at the Curragh.
O'Brien said: "He's fine. He's a very relaxed horse and good enough to compete. Marco Botti did a great job with him, but he's a year older and has strengthened up.
"It will be interesting taking on Frankel and if you know his achilles heel, I wish you'd let me know!"
O'Brien has also left in multiple Group One winner So You Think, but has confirmed he is highly unlikely to take part.
"We gave him a bit of a break after Dubai and we'll wait a bit longer with him. He'll probably run in the Tattersalls Gold Cup at the Curragh (May 27)," said the trainer
The Ballydoyle team have a third entry in likely pacemaker Windsor Palace.
