With children's photos and a side swipe: Schweinsteiger congratulates Neureuther on his big birthday. The two can be seen as children in ski outfits, at a joint press event and in the Allianz Arena.

The soccer world champion adds a wink emoji after it - alluding to a well-known chapter from their shared past. There was no immediate and public reaction to the little swipe - at least initially. Neure Luther, who recently spoke about his late mother Rosi Mittermaier, should come up with something else.
