Ajax coach Peter Bosz says the club is sorry Zlatan Ibrahimovic will miss the Europa League final tonight.
The United striker will be in Stockholm, but only as a spectator due to a serious knee injury.
Ibrahimovic is a former Ajax player and Bosz says: "He is part of the Ajax history.
"This guy has had an incredible career and has so often become a champion in different countries. He had to play this final.
"Unfortunately, he is injured and he is not there. We will miss him in the final."
