For Zlatan maybe this will be the end for him as previously promised because regardless of his current age it is enough to retire there even he can retire with pride because he can win the title in his last season
Winning the title at the end of the season and scoring 8 goals and 3 assists in 23 appearances in Serie A seems very special to a 40 year old man like ibrahimovic. It was a huge achievement for him and now I think he is very proud to announce his retirement
"if he will do it this time". It will be difficult for Milan to achieve the same feat next season
"although it is possible" if Ibrahimovic decides to continue his career, so retiring is the right choice for him in my opinion.
True, this was a good opportunity for him because with this result at the age of 40 now it could be said that this was a good achievement and even only a handful of people were able to achieve this feat.
But indeed this also depends on the decision that Zlatan Ibra wants to make because he really likes to exploit himself and always challenges his body's strength. But if he doesn't do this now I'm not quite sure an opportunity like this will come back to Zlatan in the future
