It was confirmed by AC Milan some time ago and in the near future he will be ready to return to the field. The confirmation give by Milan is that it will take at least 7 to 8 months for Ibrahimovic to recover after undergoing surgery on his left knee. Instead I'm more worried that his contract at Milan will end soon, Milan still hasn't given any clues regarding the extension of Ibrahimovic's contract. But even though Milan have no intention of extending it, several clubs are willing to invite him to play
AC Milan respected what Ibrahimovic has done for them and they are treating Ibrahimovic very well. Ibrahimovic can stay in the club, can retire or can move to another club. AC Milan don't reject to allow him to stay. It is their respect and fairness only. Ibrahimovic at his age and his latest injuries has his serious serious issues. He no longer has his best health and his time is counting down. I know if Ibra is healthy, he can make Ibracada and score amazing goals.
Zlatan Ibrahimovic lifted the scudetto with AC Milan this season, it may be his last because Zlatan is aging and has clock his 40 which makes him the oldest player in AC Milan 2021/2022 campaign. Zlatan have many titles to his gallery and he's still looking for a contract extension with the Rossoneri but talks have not been open yet. Milan boss, Stefano Pioli is still in pursuit of new players in the transfer window. He has already added Divock Origi from Liverpool, the new attacker is always lucky infront of goals despite his unregular starts in Liverpool games.
Even Ibra contribution is small because he missed of the last match because of months with injuries, his strong mentality contributes to his young team mates. They have been growing up in last 3 seasons with lot of inspiration from Ibrahimovic. We see how they celebrated their Scudetto and how they respected Ibrahomic.
Divock Origi is not actually a too good striker. His career so far shows it and he is not at the top class level as Ibrahimovic
Actually happy that Ibrahimovic is still able to compete in the big league series A. At 40 years old he can still take advantage of the advantages he has, even though he doesn't run much he is quite effective at creating chances for himself or friends. Milan may have been worried about his age and injury, that's why they bought Origi to replace him next season. Even though I haven't seen a lot of performances, I think he only got enough playing time. Maybe with his move to Milan, he can show his best abilities. Hopefully he can adapt quickly.
AC Milan and Serie A are good for old players. Matches there don't require too much fighting face to face, not mainly based on strength or speed of players. They are a league that prioritizes tactics. Their Catenaccio tactic is one of the most famous and has many decades but still has good effects in modern football.
I hope that Ibrahimovic will win Champions League next season with AC Milan too. Then he can retire as a legend.
