Donna will find herself in a completely new situation - to be the team leader
A lot of pressure on young shoulders, that's for sure, but it could actually do a lot of good for her confidence as well. Yes, Jurak would be a good replacement considering she is not defending any major points until later in the month and would be an amazing help for doubles. Savic is probably out of the question cause she's already in Australia getting ready for tournaments and to cancel all that off and come to Israel would be asking for a lot. Vrljic wouldn't be of much help ATM due to her recent (in)activity and questionable form.
