Fresh from the eight-goal salute to Arsenal, another attacking frenzy was underway. Hernandez appeared to have turned in United’s fourth just two minutes later, but his neat finish applied to a Nani cross was correctly rendered illegal by an assistant’s flag.
The game lulled for the final third of the half, as rampant visitors and shell-shocked hosts drew breath. Kevin Davies swiped air rather than ball after a decent Martin Petrov cross and Nani fired into the side-netting from close-range, but the interval came with United exuding comfort.
Were any reminder required that Bolton can never be taken lightly, especially at home, it was served by Klasnic within two minutes of the restart. Fortunately, De Gea had the smart reflexes and handling to field the Croatian's low snapshot.
At the opposite end, Jaaskelainen did well to flick Anderson's wicked free-kick wide of the post, but relied on his defenders to dig him out of a hole after Hernandez had stolen possession outside the area. The Mexican didn't have to wait long, however, to double his tally, sliding home from close range after Michael Carrick's shot had rolled through a thicket of bodies.
Bolton's response to the fourth goal was positive, as Nigel Reo-Coker crashed a shot against De Gea's crossbar, before both sides rang the changes. Kevin Davies made way for David N'gog and Darren Pratley replaced ex-Red Chris Eagles for the hosts, while Sir Alex introduced Ryan Giggs and Smalling at the expense of Ashley Young and the limping Evans.
