I think it's OK to ask the question about the locker room, because it is something a lot of people will wonder about, but they need to stop asking it after the first couple of days.
Why would the locker room be a problem? The girls mostly have male coaches,
As Sparkle says it probably will make some people curious as it's so unusual for a male player to have a woman coach, but I'm sure there must be times when players don't want to talk to their coaches in the locker room anyway, so it makes sense that other facilities are available.
She also said his group is fun and she is so serious.Coaching Llodrawho Andy said is a real joker,she is telling fibs me thinks.
That crossed my mind too. Also you can see in the videos that she has a sense of fun, and Andy would never appoint anyone unless he was sure they had a good chance of fitting in with the rest of his team given that harmony is the key for everyone to work together successfully.
She is certainly a lot better looking than Lendl. This is key in my opinion.

The other thing that I like, and which nobody seems to have mentioned, is that she's so close to Andy in age. I'm not quite sure why, but I think this could be quite beneficial for him than having another older coach. Maybe it's because I wasn't too keen on the sort of cosy father/son relationship he seemed to have with Lendl. After all the player is the employer and his/her coach their employee, so obviously while it's essential that they get on and have respect for each other, I think it's important there should still be a little distance between them.
