This is reported by the site of competitions.
As noted, the main motive for the termination of cooperation for Manchester United is the high salary of 35-year-old Zlatan Ibrahimovic.
In addition, due to a serious injury, he missed the end of the 2016/17 season. In this regard, the club does not intend to pay a lot of money to an age-old football player who will miss half of the football year.
Nevertheless in the season 2016/17 Ibrahimovic scored 28 goals and gave 10 assists in all tournaments.
Recall, as previously reported, "URA-Inform", the hero of the match 1/16 finals LE "Manchester United" against "Saint Etienne" was Zlatan Ibrahimovic, having issued a hat-trick at the "Old Trafford".
