Chris Eagles and Patrice Evra both got on the scoresheet as United trounced FC Seoul 4-0 in the Reds' second pre-season tour match.
United, inspired by an effective and entertaining performance from Cristiano Ronaldo, were clinical in front of goal and sped to a 3-0 lead after just 21 minutes. Evra capped the scoring on the hour to seal an impressive win in front of a fanatical Korean crowd.
The Reds made four changes to the side that started against Urawa Red Diamonds on Tuesday, with Paul Scholes, Ryan Giggs, Wes Brown and Darren Fletcher all rested. Injuries again prevented fans from getting a first glimpse of new signings Owen Hargreaves and Nani, but Sir Alex handed starts to Chris Eagles and Phil Bardsley. Elsewhere, Mikael Silvestre and John O'Shea were called into the starting XI.
With both Silvestre and Evra in the side, the manager gave the Frenchman the freedom to push into midfield and he showed off his skills as early as the third minute with a cheeky back-heel pass.
But it was the star combination of Wayne Rooney and Cristiano Ronaldo that put the Reds in front on six minutes. With his back to goal, Rooney laid the ball square to Ronaldo who was given far too much space to run at the defence. In fact, nobody moved towards the Portuguese international, who advanced to the edge of the area before unleashing a low shot that beat Seoul goalkeeper Kim Byung-Ji at his right-hand post.
Rooney and Ronaldo carved open the defence again 10 minutes later but Ronaldo's touch was too heavy and the ball ran out for a goal kick. He got it right just nine minutes later when he cheekily dragged the ball inside to Chris Eagles on the edge of the area. Eagles, who last netted at Goodison Park in April, had time to pick his spot and curl the ball inside the left-hand upright to send United 2-0 up.
