he tried in vain to trick his way past Scott Wootton, one half of a young United centre-back duo formed with Michael Keane.
Oriol Romeu collected the first booking of the night by tripping Buttner but Nani couldn’t punish him further from the free-kick, drilling a low shot direct at Petr Cech. The big Chelsea goalkeeper also got down well to deny Welbeck during a decent spell for the Reds.
With dismissals for Fernando Torres and Branislav Ivanonic still painfully fresh from Sunday, hearts were in mouths for the home faithful when Romeu, on a yellow card, committed another foul just outside the area, on Nani. The Spaniard escaped the shame of a red card but embarrassment encircled him down moments later when he dawdled on Cech’s short goal kick and Anderson picked his pocket to present Giggs with a very presentable chance. United's record appearance maker snapped up the one-on-one opportunity, coolly curling a low finish past the hopelessly-exposed keeper.
A defensive error at the other end meant United’s lead lasted just nine minutes, albeit a blunder forced by the blistering pace of Moses. The winger was sent sprawling by Buttner’s rash challenge and Luiz, scorer of the opening own goal three days ago, tucked his spot-kick low to Lindegaard’s right to level the contest at 1-1.
If Luiz kept his head in that key moment, he lost control in the next one – gifting not only possession on the halfway line but also the space behind him for United to ruthlessly exploit. Rafael tackled him but then Anderson was the architect, driving a pass between the scrambling Cahill and Mikel into the path of Chicharito. The in-form Mexican barely needed a second glance to beat Cech for the second time in four days, taking the ball into his stride before lashing it into the same bottom corner previously found by Giggs.
