My thoughts are Douvan will go for this... After all this is a Championship race and Mullins has never won it before either.
The horse will also only be 8 years old in March. If he wins, he could stay at this trip and become the dominate 2 miler (a la Sprinter Sacre). If he loses then he always has the option of being stepped up in trip the following year when he should still be at his peak.
Obviously it depends on how well he's overcome his injury, but judging from the comments he is back to normal.
I also think Min could come here also. This is probably more dependent on what else Ricci/Mullins has for the Ryanair though (American Tom potentially), but if Mullins thinks they're both true 2-milers then I think he'll throw them both at Altior.
Imagine that race, including Great Field
