MANCHESTER, England (Reuters) -- Wayne Rooney and Park Ji-sung both scored twice, with Cristiano Ronaldo making three of them, as Premier League leaders Manchester United romped to a 4-1 home win over Bolton Wanderers on Saturday.
Ronaldo provided the cutback for Park to score United's first after 14 minutes, he put Rooney through for the second and then hit a shot which keeper Jussi Jaaskelainen spilled and Park tucked home in the 25th minute.
The winger got a standing ovation from the Old Trafford crowd in the 70th minute when he was replaced by Alan Smith, who promptly set up Rooney for his second of the afternoon on the break.
Gary Speed scored Bolton's consolation goal from the penalty spot three minutes from the end.
The victory, which sent United nine points clear before second-placed Chelsea kicked off against Sheffield United, was marred though by the loss of United's England defender Gary Neville to an ankle injury after nine minutes.
The injury was the only cloud over an imperious performance by United, and by Ronaldo in particular.
His scintillating pace and close ball control took him to the very limit of the bye-line after 14 minutes before he deftly picked out Park for a powerful sidefoot home.
He linked up superbly with Rooney minutes later as the two forwards surged forward on the counter-attack, feeding the ball through for the England striker to dink over Jaaskelainen and claim his 50th goal for United.
Bolton's keeper could not hold a stinging Ronaldo shot shortly afterwards and Park was first to the loose ball, steering it into the gaping net.
Rooney rounded off the scoring with a calm finish after galloping through on the break, the early kickoff's one positive for McClaren.
Paying tribute to Ronaldo, Ferguson said: "His season has been incredible, you can't put one game in front of another as far as I'm concerned because he's given his all in every game.
"Today, particularly in the second goal, the combination between him and Wayne Rooney -- and his weighted pass to Wayne to finish things off -- was tremendous."
Chelsea remain in touch
Meanwhile, Chelsea remain six points behind in second place after a comfortable 3-0 victory over Sheffield United.
First-half goals from Andriy Shevchenko and Salomon Kalou and a headed third from substitute Michael Ballack proved enough for the reigning champions.
Struggling Manchester City got a morale-boosting 2-0 win at Middlesbrough. French defender Sylvain Distin and Belgian striker Emile Mpenza, his first for the club, were the goalscorers.
Tottenham Hotspur beat relegation candidates Watford 3-1, including a goal from a free-kick by Spurs' England goalkeeper Paul Robinson.
Along with Robinson, whose booming kick bounced over England understudy Ben Foster, Tottenham's other goals came from Jermaine Jenas and Hossam Ghaly.
West Ham moved off the bottom with their first away win of the league season, a highly-controversial 2-1 victory over Blackburn Rovers at Ewood Park.
Blackburn led through Christopher Samba, West Ham levelled with a penalty from Argentina's Carlos Tevez and Bobby Zamora claimed a 75th minute winner with a shot that struck Tevez -- who was standing on the goalline and bounced out.
There were 0-0 draws between Reading and Portsmouth, along with Wigan Athletic and Fulham.
