Man United beat Liverpool despite nervy ending

Premier League leaders Manchester United and second-placed champions Manchester City put former English heavyweights Liverpool and Arsenal firmly in their place on Sunday with United's Robin van Persie again on song.

United sealed a needlessly nervy 2-1 home win over eighth-placed Liverpool to maintain their seven-point lead after Van Persie with a goal and Patrice Evra with two assists put rival Luis Suarez in the shade.

In contrast, the game in London was never in doubt with City winning 2-0 for their first league win at Arsenal in 38 years.

City were given a helping hand by the 10th-minute dismissal of Arsenal's Laurent Koscielny for wrestling Edin Dzeko to the ground before James Milner and Dzeko netted before the break.

Liverpool have had to watch with horror over the last two decades as big rivals United undisputedly crowned themselves kings of the English game, trampling over the Anfield side's legacy after they had shone the brightest in the 1970s and 80s.

The first half at Old Trafford, which followed United's 2-1 win at Liverpool in September, suggested talk of the balance of power should be replaced by whisperings of the huge gulf in class such was the ineptitude of Brendan Rodgers' side.

Dutchman Van Persie, English football's in-form striker along with Liverpool's Suarez, grabbed a 19th-minute opener when he swept in Evra's cross in inimitable style.

"Robin van Persie is different class. He produces moments in the game others can't do and we are glad he is on our side," man of the match Danny Welbeck told Sky.

"We had our gameplan and it worked really well in the first half. They came into it more in the second half but we got the three points and showed our character."

Forward Welbeck, preferred to the in-form Javier Hernandez in the absence of the injured Wayne Rooney, justified his start with some good play although he should have done better twice in the first half when almost clean through.

Van Persie, who now has 17 goals as the league top scorer, had another chance just before the break as United overran their toothless north-west neighbours but he oddly chose a cheeky flick which Martin Skrtel cleared just before the line.

FORGETTABLE PERFORMANCE

Uruguay's Suarez, with 15 league goals this term, was often jeered by the home crowd in a forgettable performance where nothing went right but he took the sting out of any more vocal taunts by shaking Evra's hand before kick-off.

Suarez failed to do so last season at Old Trafford after serving an eight-game ban for racially abusing the Frenchman.

The arrival of the lively Daniel Sturridge at half-time for his Premier League debut after joining from Chelsea and the fact they somehow went into the break just 1-0 down boosted Liverpool's confidence in the second half.

It was soon dampened when Van Persie's free-kick was headed goalwards by Evra, prolific for a left-back with four goals this term, and the ball deflected off team-mate Vidic before bulging the net. No Liverpool players appealed for offside but replays showed the Serbian was just ahead of their back-line.

Liverpool's defence and especially Johnson had been found wanting for the goal but Sturridge dug them half out of a hole when he struck after 57 minutes when Gerrard's pil
