Lazareva didn't really convince me as Goncha's backup with the little matches she has played. I argue even Arina would make a better backup Opp than her. I would take Smirnova as second Opp at least she can be useful as a serving sub
thinking about it you are right. And atleast Smirnova can be useful a bit in defense at the back.
the glaring weakness in the serve-receive and defense was so shocking and was super exploited by the opponents.
