Still can't see her troubling the Arc principles despite overcoming this.
the proximity of Cirrus Des Aigles on her two starts (also if you believe Planteur ran to form at Ascot then he's a good marker for the form again), it puts the form into perspective; he's a very talented Group Two horse but is only that.
I think you are being mischievous now. It would have taken some horse to finish far ahead of Cirrus Des Aigles off that pace giving him the start that she gave him.
