Paul Pogba was tightlipped about his future at Manchester United after the friendly win against Perth Glory.
Second-half goals from Marcus Rashford and James Garner proved decisive at the Optus Stadium.
Pogba provided the assist for Rashford in his first game since stating a desire to leave Old Trafford, a view that has been reinforced twice since by his adviser Mino Raiola.
The midfielder declined to speak to reporters after the game, saying there was "no need" to do so.
Real Madrid and Juventus are both interested in the 26-year-old, although neither club has made a bid. United are understood to value Pogba at over £150m.
