Robert Lewandowski has strained a ligament in his right knee.
The FC Bayern striker will be out for around four weeks. After Poland’s 3-0 win over Andorra,
Lewandowski returned early to Munich, where a diagnosis was made by the German record champions’ medical team.
The 32-year-old had scored the first two goals in Sunday’s match, before having to leave the field after an hour following a clash.
