So what is the plan? Is this a win-win strategy that will help both players for the clay season, or does it have no real significance?
Is Federer doing his part as a veteran to train the youngsters for a specific purpose, to share some of his experience, looking to see what they have in their arsenal, or is he just a nice guy?
Last year he trained with Kyrgios prior to RG/Wimbledon and Kokkinakis prior to AO.
What about it, will he help Thiem improve his slice? Will Thiem return from way back like Nadal?
