Zlatan to continue playing past 41st birthdayZlatan Ibrahimovic has agreed a new one-year deal at AC Milan to extend his playing career into a 23rd season, Sky in Italy understands.Ibrahimovic, who will be 41 in October, has missed most of Milan's Scudetto-winning season due to injury and he became a free agent when his deal expired last week.The Swede has suffered from a chronic issue with the anterior cruciate ligament in his left knee and underwent an operation to resolve it immediately after the end of the season.AC Milan said in a statement that it would take him seven to eight months to recover, meaning he will likely be out of action until the new year - but he is determined the layoff won't spell the end of his playing days."For the past six months I played without an ACL in my left knee," Ibrahimovic wrote on Instagram in May. "Never suffered so much on and off the pitch."In my mind I had only one objective, to make my teammates and coach champions of Italy because I made them a promise. Today I have a new ACL and another trophy."Ibrahimovic will sign his new contract in the next few days and will lower his wages to around £1million per year, plus performance-related bonuses.The club views the veteran striker as a pivotal figure for his influence inside the changing room, as his mentality and presence proved an inspiration for their Serie A title win - their first in 11 years.He played 27 times across all competitions for AC Milan last season, scoring eight league goals.AC Milan have signed former Liverpool striker Divock Origi on a four-year deal and will count on him to lead their line next season alongside ex-Arsenal and Chelsea target-man Olivier Giroud.
