United's mesmerising start to the Barclays Premier League season continued with a five-goal stroll at Bolton's Reebok Stadium, as Javier Hernandez struck his first goals of the campaign and Wayne Rooney extended his fine form with a second successive hat-trick.
The Reds turned in a devastating showcase of finishing, bagging three goals inside the first half-hour and a further pair after the break, and also demonstrated promising defensive resolve in the face of a characteristically direct bombardment from the hosts.
The only sour note of the afternoon was a derivative of the Trotters' trademark vigour, as Tom Cleverley left the Reebok Stadium on crutches after a heavy challenge from Bolton skipper Kevin Davies, having apparently suffered a damaged ankle.
Hitherto, Sir Alex Ferguson had enjoyed good news with injuries after the recent international break, and made only minimal changes to the line-up which started last month's romp against Arsenal. Danny Welbeck, who suffered a hamstring strain against the Gunners, was replaced by Hernandez, while Rio Ferdinand returned at the expense of Chris Smalling and Phil Jones shunted over to right-back.
As had been the case in the Reds' opening three league games, United began in proactive fashion. Indeed, it took the visitors just five minutes to forge ahead. As a United attack built on the right wing, with Rooney releasing Nani, Chicharito outwitted Gary Cahill by shaping to move to the near post, feinting to the back and then sprinted forward just in time to redirect Nani’s centre past the sprawling Jussi Jaaskelainen.
