Marco Botti hopes the going at Newmarket doesn't get too soft for his two runners in the Princess Of Wales's Goldsmiths Stakes on Thursday.
Jakkalberry and Joshua Tree have been declared to run but both have big international targets later in the year and are best on top of the ground.
The former, who captured the Group One Gran Premio Di Milano for Botti's cousin Endo in June, 2010, heads to the July Course after coming home fifth behind Sea Moon in the Group Two Hardwicke Stakes at Royal Ascot on June 23.
The six-year-old started the year with a pair of fine efforts in Dubai, including when coming home a fast-finishing third in the Group One Dubai Sheema Classic at Meydan on March 31.
Botti said: "Jakkalberry has come out of Royal Ascot in good order. We are just monitoring how much rain there is at Newmarket because he is a fast-ground horse - he would be fine with a little bit of cut in the ground but he wouldn't want it too soft.
"I think that he has definitely come on for his run in the Hardwicke Stakes. We gave him a break after he came back from Dubai and that race will have brought him on. His run in the Dubai Sheema Classic, when he had ideal conditions, was probably his best run to date.
"We are aiming him at the Melbourne Cup this year and there are a couple of options before then. He could head to Chicago in August or the Geoffrey Freer Stakes at Newbury."
Joshua Tree, successful in the Grade One Pattinson Canadian International for Aidan O'Brien in October, 2010, finished fourth on his latest start in this year's Group One Gran Premio Di Milano on June 10.
The son of Montjeu also started the season in good form at Meydan, culminating with a staying-on second in the Group Three Dubai Gold Cup over two miles on March 31.
Botti added: "Joshua Tree ran a good race in Italy. Being by Montjeu, he gets away with a little bit of cut in the ground but he wouldn't want it too soft either. He is a solid old horse and he ran some nice races out in Dubai at the start of the year.
"We are keen to get a run into him because we want to keep him fit for the new race on the Arlington Million card over a mile, five and a half furlongs. He's a horse who takes a lot of work so we need to run him to keep him fit."
