But hours after United added a friendly in Sweden to their pre-season schedule Ibrahimovic ended a game of cat-and-mouse he has enjoyed playing with the media since announcing his departure from Paris Saint-Germain.

He will now attempt to win a league title in a fifth major European league, under the guidance of Jose Mourinho, his former Inter manager.

The pair's mutual admiration has long been a matter of record, and they share a common enemy in Pep Guardiola, who clashed with both during his time at Barcelona and will be in charge of United's cross-town rivals City next season.

Ibrahimovic will be joined at United by incoming center-half Eric Bailly, while a fee has been agreed for Borussia Dortmund's Henrikh Mkhitaryan.
