Can't see any confirmation on this. The timing seems a bit strange - i.e. the day before the Euros start and it's not as if she's just out of contract (her current deal expires in 12 months time).
Anyway, it looks like she's more of an attacking midfielder than a central one, and in one listing of Germany's squad I saw she is identified as a forward. So arranging the non-defence in a 2-3-1 formation she's more in the 3 than the 2 (so most like half our squad). Looks to be a Roord replacement.
I went down a bit of rabbit hole looking at various Euro previews. The takes from these are:
1. She's on the fringes of Germany's starting 11. It's about 40/60 whether she starts or not. Knaak on the other hand is expected to start.
2. Beney is expected to start for the Swiss. In terms of our squad, she looks to be cover for Fujino. I do wonder whether we'd have signed her if Mary hadn't done her ACL.
3. There was a fair degree of positivity about our new manager (assuming it is Jeglertz).
