The results of the scan showed Milik has ruptured the anterior cruciate ligament in his left knee.

And his club confirmed that he had suffered a "total rupture" of the ligament, which could leave him on the sidelines for around six months.

"Arkadiusz Milik was evaluated under MRI today after his injury suffered playing for Poland," a club statement said.

"The tests confirmed that he has experienced a total rupture of the anterior cruciate ligament in the left knee. The Napoli striker will undergo surgery tomorrow morning."

Since moving to Serie A from Ajax at the start of the current campaign, the 22-year-old has scored seven goals at club level in all competitions.
