Pijnaker played 2nd half for a youthful Grasshopper FC first team a few days ago, in a trial against Basel U21.

After the break, Forte left the same team on the pitch except for one position: only Nando Pijnaker came into play for Elias Mesonero.
Seems like they are having a serious look at him.
I remember their signing of Mata dragged out for months. Work permits slow to process in Switzerland??
Swiss season resumes for Grasshopper (2nd tier) tomorrow.
