Manchester United's deal for Zlatan Ibrahimovic has hit a major glitch with the striker willing to participate in the Olympic Games scheduled to be held in Rio in August. This will rule him out of United's pre-season tour and also make him miss the Premier League opener which is scheduled for Saturday, 13 August.

The Mirror reports that Sweden Under-21 coach Hakan Ericson wants Ibrahimovic to be one of the three players above the age of 23 in his squad and go for gold in the biggest sporting event of the year. The 34-year-old is already participating in the Euros and will have only a gap of two weeks to rest should he decide to fly off with the team for the upcoming tournament.

Jose Mourinho, United's manager for next term, has offered him a one-year contract but the deal is now in peril over his decision to choose his country over his commitments to the club. The Red Devils have a major money spinning tour of China before the start of the season and Mourinho will be desperate to hit the ground running before embarking on his new role in the Premier League.

The Swede played under Mourinho when both were at Inter Milan and enjoyed success with the Serie A outfit. The former Chelsea boss now wants to bring Zlatan with him to England and make him the focal point of United's attack, which has struggled to score goals under Louis van Gaal.

His move to Old Trafford is being held up over a £1m ($1.43m) loyalty bonus from his current club Paris Saint-Germain, which will elude him should he make the move before June 30, when his contract expires. United currently have only Wayne Rooney and Anthony Martial as possible options up front and are likely to invest heavily to rejuvenate their squad for the upcoming season.
