Ibrahimovic scored a team-best 28 goals in 46 games for Manchester United in his only season with the club. The Swedish striker will be added to the club's release list which will be sent to the Premier League tomorrow, according to Sky Sources.

Ibrahimovic's current deal expires at the end of the month, but United have the option of a 12-month extension when it is complete.
