New signing Nani scored on his debut as United ran riot against Shenzhen FC in a humid Macau Stadium.
The summer signing hit the Reds' third after just 23 minutes in a game that felt more like a practice match than a pre-season showpiece. Shenzhen rarely troubled United's rearguard and Sir Alex may have preferred a sterner workout. But the Reds did provide plenty of entertainment, including spectacular goals from Wayne Rooney and Chris Eagles.
Only five players who started against FC Seoul last Friday kept their place in Macau, with the manager handing starts to a number of youngsters. Nani operated on the right side of midfield, while Jonny Evans partnered Nemanja Vidic in central defence. Paul Scholes' injury-enforced absence handed Darron Gibson a chance to prove himself in central midfield and he looked lively early on when he combined with Wes Brown to force a corner in the third minute. Cristiano Ronaldo rose highest to head the cross past Shenzhen goalkeeper Jianjia, but the referee had already blown his whistle for a foul.
But the Reds continued to press and duly took the lead after 12 minutes. Rooney collected a curling Darren Fletcher pass inside the area and headed straight for goal. But while everyone expected the England forward to shoot, Rooney squared the ball inside to Ryan Giggs who rolled the ball into an empty net for a deserved lead.
The home side looked comparatively ineffective going forward but could have equalised had the referee spotted Evans' 15th-minute handball as he attempted to block a cross. United took advantage on 20 minutes via another moment of magic from Rooney. This time it was Giggs who provided the splitting pass into the area. Rooney controlled the ball before sending a superbly disguised chip over Jianjia - a sublime piece of skill that called to mind a similar pre-season effort in 2005.
