I have reservations aout this pairing. If Anna's serve goes off, can Elena imbue her with confidence, the way Martina could? Can Elena help Anna to relax at crunch time, the way Natasha Z or Chanda sometimes could?
If Elena is the one who struggles, will Anna be able to give her the encouraging word, to let her know "I have confidence in you"?
So I don't see a future of greatness for this team, but they do have a good draw to the semis, and even that would certainly feel great for both of these players right now.
