It's just going to be Gosviani because Leonova in the final can't make any mistakes. What if she pops a jump? Then it's well Leonova hasn't improved. So she can't fall at all or single one jump.
I agree: this skate will be a key one, I think that (unless Lipnitskaya or one between Liza/Adelina has another injury next season) this is her last opportunity to make the World team, especially thinking that in 2014 Radionova will be eligible, too... But I expect it to be Gosviani, though: she skated well at Euros and, even if her performance was not like Korobeneykova's 2012 one, she looked a lot less nervous than Polina, so I think that she is a tougher skater, mentally: she could be able to skate like this again at Worlds, I think, she doesn't think she is a diva (she didn't place in the top 3 in any of the two programs), so I think that she wouldn't have a lot of expectations if she was sent to Worlds, she would just focus on skating her best...This will be probably be Leonova's most important event as if she missed this out
we may not see her again same with Makarova, next season she may be of no use anymore
as more younger girls will be eligible for full seniors next season, Julia L. Anna P. just to name a few.
