Cityscape in Lockinge frame
Cityscape may be re-routed to the JLT Lockinge Stakes if Frankel misses his intended reappearance through injury.
The six-year-old, owned like the highest-rated horse in the world by Khalid Abdullah, was the most impressive winner of Dubai World Cup night in the Dubai Duty Free.
He does have options abroad but trainer Roger Charlton is prepared for him to run at Newbury on May 19 instead.
"He's really well and as he's a good traveller he's got options abroad," said Charlton.
"The BMW Champions Mile in Hong Kong on May 6 is an option as it's worth £550,000 to the winner but I suppose it depends on Frankel.
"If Frankel doesn't run in the Lockinge, Prince Khalid may want Cityscape to run there instead, it's up to him."
