Manchester United gained their best pre-season victory so far by beating Barcelona 3-1 in front of 68,414 at Levi's Stadium in Santa Clara, California.

Wayne Rooney's eighth-minute header from Ashley Young's corner put United in front.

Jesse Lingard doubled the lead when he swept home Tyler Blackett's cross after Louis van Gaal had replaced his entire starting XI just past the hour mark.

Rafinha's splendid volley in the final minute was followed almost immediately by United's third from Adnan Januzaj as Van Gaal's team struck on the break.

Victory over the European champions is a welcome sign of progress for Van Gaal - particularly in attack - although Barcelona did hit the woodwork on three occasions, twice through Luis Suarez, who also had a goal disallowed for offside.
