3 things to think about.
1. As far as I know, German Fed and Kerber doesn't have the best relationship. Will they be able to work together?
2. Does Kerber even want to play for Germany? She actually wanted to represent Poland but was not turned down by the Polish Fed.
3. ALG is still a good doubles player. Without her, who would become Germany's doubles team?
I'm able to work with people I don't like and who don't like me every day of the week. Those two should manage to get along for a few days or seriously think about improving their people skills.
According to a German interview she gave, the Poles wanted her and she turned them down in favor of good ol' GER. God knows what she told the Polish media.
That she's wholeheartedly German is very
questionable, though. Saying she's German to German media and Polish to Polish media is just wrong and she must be bullshitting somebody and I feel like it's us. As long as she plays for us I don't really care. Let's face it, there's a lot of German footballers (to name one sport) who would've turned their back on the nation that made them the athletes they are if we weren't among the best in the world. (Just look for the guys who don't sing the anthem.
Chemistry-wise Petko/Angie would work, I think. Maybe the Polish girls Bine/Angie could work together as well. Realistically, I think the doubs needs to include Jule, since she's the best in doubs and the least consistent in singles. On the other hand... it's clay, so maybe she'll be good again.
It's all very complicated and as I said before: I wouldn't wanna trade with Barbara.
