Silvia Lore/Getty Zlatan Ibrahimovic led his team to victory without an ACL in his left knee
"For the past six months I played without an ACL in my left knee. Swollen knee for six months. I was only able to train with the team 10 times in the last six months," Ibrahimović, 40, wrote on Instagram.
According to Italian journalist Fabrizio Romano, AC Milan confirmed that Ibrahimović underwent surgery on the knee and will spend the next seven to eight months rehabbing.
"In my mind I only had one objective, to make my teammates and coach champions of Italy because I made them a promise," the Italian soccer star wrote of helping his team bring home their first title since the 2010-11 season on Sunday.
The athlete told his social media followers that his days during the last six months have included "more than 20 injections" and managing the severe pain with painkillers "every day."
"Barely slept for six months because of the pain," he wrote. The soccer star said he has "never suffered so much on and off the pitch."
