Flick has made two changes on the back of Bayern’s 2-0 win over Augsburg on March 8. The two-month break has given the division’s leader goalscorer Lewandowski a chance to recover from a knee injury, and it is no surprise to see him return to the side in place of the benched Zirkzee. The other alteration comes in attacking midfield as Goretzka replaces Philippe Coutinho, who underwent surgery on his ankle in April and is out for the foreseeable future.
